The advertised match may be split across deposits or tied to limits and conditions that determine whether bonus funds can become withdrawable.

What a 500% Bonus Really Adds Up To

A “500% bonus” sounds like the casino has decided to throw money at you. I have made that mistake before. The large percentage catches the eye, while the structure hiding behind it gets ignored.

A 500% match means the advertised bonus is five times the qualifying deposit. Put simply, a deposit of £10 would produce a stated bonus of £50, provided that the offer is calculated that way. That is the headline maths, not a promise that £50 will arrive as withdrawable cash. The casino may attach a maximum bonus, split the promotion into stages, or make the headline figure depend on several separate deposits.

That last point matters more than the percentage.

The headline may cover several deposits

Some offshore welcome packages are built as a sequence rather than one large reward. The first deposit may unlock one part of the promotion, with later deposits unlocking further parts. A page can therefore advertise a total worth exceeding £5,000 while the player receives nothing close to that amount from a single transaction.

A specialist review has described offshore packages in this format: several deposit stages combined into one large advertised value. That description should not be read as proof that every casino offering a 500% casino bonus follows the same pattern. It shows how the number can be made to look much larger than the first reward you actually see in the account.

The wording can be slippery. “500% welcome bonus” might refer to the whole package, while the first stage is much smaller. Alternatively, the percentage may apply only within a stated ceiling, after which further money deposited produces no additional bonus. The total shown in promotional material may also combine separate rewards that become available only after separate qualifying deposits.

So when you see an online casino with a 500% bonus in 2026, ask yourself what the percentage describes: one deposit, a capped stage, or the combined value of the entire welcome package?

That is the useful question.

Five times the deposit is still bonus money

The other trap is treating the displayed bonus as though it were part of your bank balance. It is not. A casino may show the deposit and bonus together in your account, but the bonus portion remains promotional funds until the offer’s conditions have been satisfied.

This is why a large advertised total is not the same as cash you can withdraw. The value depends on the reward itself, your eligibility, the qualifying deposit, the games that count, the expiry period and the withdrawal conditions. A 500% casino deposit bonus can look generous on the offer page and become far less attractive once those separate conditions are read together.

I now treat the percentage as an upper label, not as money in hand.

There is another distinction worth keeping clear. A 500% match does not mean the casino is giving you five times your deposit with no further requirements. It means the promotional balance is calculated using that rate, subject to the offer’s rules. Any winnings made while using bonus funds can also remain restricted until the relevant conditions have been met.

That does not make the offer worthless. It simply makes the headline incomplete.

The wider market picture

The most eye-catching 500% offers are often associated with offshore operators rather than British-licensed casinos. That difference is not just cosmetic. Offshore operators do not operate within the UK Gambling Commission system. They also do not provide GAMSTOP coverage or the UKGC dispute-resolution route, and they are not required to apply British stake limits or bonus rules.

For anyone in Great Britain, a remote operator selling gambling services into the market must hold the relevant UK Gambling Commission licence. Online gambling is legal here at licensed and regulated sites for players aged 18 and over. An offshore casino may still be accessible, but accessibility is not the same thing as British regulation.

Offshore operators do not operate within the UK Gambling Commission system. They also do not provide GAMSTOP coverage or the UKGC dispute-resolution route.

That is why the “best 500% casino bonus UK” is not automatically the offer with the biggest percentage. A huge offshore package may advertise more promotional value, but it comes without the protections attached to a UKGC-licensed operator. Before depositing, I would check the operator’s licence on the UK Gambling Commission public register rather than relying on a banner or review badge.

The comparison is also affected by the way wagering is presented. A specialist review has reported wagering figures of 25x to 35x across international markets, compared with an industry standard of 40x or higher on UK sites. That is a comparison from that review, not a rule applying to every casino in either group. A lower stated multiple can make an online slots 500% bonus appear easier to clear, but the percentage, the eligible stake and the games that count all matter together.

More bonus is not automatically better.

Read the total as a calculation

When assessing a 500% match bonus, separate four things in your head:

• the rate applied to the qualifying deposit;
• the maximum amount available at that stage;
• whether the advertised total combines several deposits;
• whether the bonus balance is cashable or restricted.

This prevents the familiar mistake of seeing a very large figure and assuming it represents money you can withdraw immediately. The same applies whether the page calls it a 500% slots bonus, a 500% welcome bonus or a 500% casino match bonus. Different wording can describe the same basic promotional calculation.

The percentage tells you how the reward is measured. It does not tell you what the offer will finally be worth.

Your First Deposit: Where the Match Starts

A 500% first deposit casino bonus in the UK sounds as if the whole deal appears the moment you open an account. That is not how I would approach it. The first deposit is the point at which the welcome offer is tested, and a missed step can leave the promotional balance behind before you have even started playing.

The basic sequence is straightforward: register, opt in to the welcome offer, and make the qualifying deposit. A specialist review describes those three actions as the route players use to claim a welcome offer. The wording matters. Creating an account alone does not claim the bonus, and depositing alone may not do it either if the promotion has not been selected.

Casino Bonuses in the UK: No-Deposit and Welcome Offers

Start with the account, not the deposit

Use the casino’s registration form and provide the requested personal details accurately. A UK-licensed operator must verify your age before allowing you to deposit, so the account may not be ready for gambling immediately after the form is submitted. That check is not an optional extra attached to the bonus; it is part of opening a real-money gambling account.

New customers must also be prompted to set a financial limit before their first deposit. I see this as a useful pause, especially when the offer is dressed up as a “500% boost”. That phrase can make a small deposit feel like the beginning of something much larger. Setting the limit first keeps the decision tied to the money you actually intend to spend, rather than to the promotional headline.

Before adding funds, check that the account is at a UK-licensed casino. Remote operators selling gambling to Great Britain must hold the relevant UK Gambling Commission licence, and the licence number should be checked on the Commission’s public register. An offshore site may show a large welcome package, but it does not sit inside the UKGC system. The bonus is not a reason to skip that check.

Opt in before putting money down

Once the account is open, find the welcome offer and opt in if the casino requires that action. Do not assume that every promotion is attached automatically to a new account. The offer should make clear whether you have selected it and what deposit qualifies.

This is where the idea of a “500% deposit bonus” can become slippery. The headline may refer to a package arranged around the customer’s early deposits rather than a single credit applied without conditions. A specialist review describes one structure in which the first deposit carries a 100% match up to £500, while later deposits have 50–75% match rates and may come with separate free-spin allocations. That is an example of how a large package can be staged, not proof that every casino with a 500% offer handles the first deposit in that way.

So I would read the first-deposit line on its own. What deposit qualifies? Is the offer for new customers only? Does the account need to be opted in before funds are added? Does the promotion exclude a particular deposit method? Those questions belong to the activation step, before the money leaves your account.

Make the qualifying deposit carefully

The deposit must be made through an accepted deposit method and meet the offer’s stated qualifying conditions. UK-licensed casinos cannot accept credit cards for gambling, including credit-card funding routed through a money service business. A wallet that permits credit-card funds to be used for gambling is also not acceptable.

I once treated the deposit button as the finish line. It is closer to the point where the casino decides whether the offer has been triggered. After depositing, check the account balance and promotional area rather than relying on a banner or confirmation page. The account should show whether the welcome offer is active and whether the deposit has been recognised.

Do not make a second deposit simply because the first one has not produced the result you expected. First check the offer status, the qualifying-deposit wording and whether registration and opt-in were completed correctly. A later deposit may be treated under a different stage of the promotion, or may not qualify for the first-deposit part at all.

The first deposit is its own stage

The first deposit is not automatically interchangeable with later deposits. In the staged example above, the opening match is treated separately from subsequent match rates. That difference is easy to miss when the promotion is presented as one large total.

Free spins can also be tied to the qualifying action rather than appearing immediately. A specialist review notes that a welcome offer may require a qualifying stake before those spins are credited. That is separate from getting the deposit match started, so I would not assume that seeing bonus funds means every part of the package has already arrived.

The sensible order is simple: verify the casino, register, complete the age check, set your financial limit, opt in, and then make only the qualifying deposit you intended to make. No rushing.

Welcome Spins and Slots: Read the Offer as Two Separate Rewards

A welcome package can show a deposit bonus beside free spins, but that does not make them one interchangeable reward. I learnt this the annoying way: I saw a large headline, treated every part of it as one pot, and only later noticed that the cash-style bonus and the spins followed different rules.

Think of the offer as two columns:

• Deposit bonus: extra bonus funds linked to a qualifying deposit.
• Free spins: a set number of spins allocated for a specified slot or promotion.

The wording may place both under one welcome banner, yet the two parts can be credited separately and used differently. A deposit bonus is generally displayed in the bonus balance, while free spins are attached to the relevant slot or shown in a separate promotional area. One does not automatically become the other.

That distinction matters when you see searches or adverts referring to a 500% welcome bonus for slots. The headline may suggest that the percentage and the spins form a single, enormous reward. It is safer to read it as a description of the promotional package, not as a promise that a percentage match is multiplied by a free-spin value. The deposit element concerns funds. The spin element concerns attempts on a slot.

What the listed examples actually show

A specialist review listing welcome offers gives several different examples rather than one standard package. LuckyMate is listed with a £10 bonus and 50 free spins. BetWright Casino and Quickbet are each listed with 100 free spins, while BetMGM Casino is listed with 200 free spins. Casumo is shown separately with a 50% deposit match up to £100.

LuckyMate

£10 bonus and 50 free spins.

BetWright Casino

100 free spins.

Quickbet

100 free spins.

BetMGM Casino

200 free spins.

Those entries should not be read as though every casino supplies all of those rewards together. They describe different offers attached to different operators. The Casumo example is particularly useful as a reference point: it is a deposit-match offer, not evidence of a 500% reward and not a free-spin allocation. The BetMGM example identifies a spin quantity, but it does not turn that quantity into a cash deposit match.

In other words, the number beside “free spins” tells you about spins. The percentage beside “deposit match” tells you about a deposit-related bonus. Mixing the labels produces the sort of inflated calculation that makes a promotion look better than it is.

Why the slot name matters

Free spins are not general-purpose credit. They are normally issued for a named slot or a defined group of games, so the offer should make clear where they can be used. If the promotion mentions slots, do not assume the spins can be exchanged for table-game play, withdrawn as cash, or transferred into the deposit bonus.

The same caution applies in reverse. Bonus funds are not free spins simply because the casino presents them on the same welcome page. A deposit bonus may be available for eligible casino play, while the free spins remain tied to their specified slot. Separate labels are not decorative. They tell you what the reward is for.

Online Casinos with Daily Promotions in the UK

I now write down three things before treating a welcome package as meaningful: the amount of bonus funds, the number of free spins, and the operator attached to each offer. That small pause prevents a list of separate promotions from becoming one imaginary deal.

A simple way to read the headline

When an advert uses language such as “500% free spins welcome bonus”, split the phrase before doing anything else. Ask whether the percentage describes a deposit match, whether the spins are a separate allocation, and which operator is actually offering each part. If the wording blurs those points, the headline is doing more work than the reward.

The useful comparison is not the biggest number on the page. It is whether you are looking at bonus funds, free spins, or a separate deposit-match offer. Keep those categories apart. Much clearer.

The Promo Code Detail That Can Decide Whether You Get Paid

I have lost a bonus before because I treated the promo code box as decoration. It was not. The deposit went through, the money appeared in my account, and the welcome offer did not. By the time I noticed, I was left trying to prove that I had meant to claim it.

Attention A promo code is not a general reference to a promotion; it is an activation detail. If the terms say that a code is needed, enter it during the deposit process.

That is the awkward difference between a coded offer and an automatic one. With the first type, the casino expects you to enter the correct code during the deposit process. With the second, the promotion is attached to your account without a code being typed. The wording on the offer page should tell you which arrangement applies. If it does not, I would not guess.

When the code is part of the claim

A promo code is not the same thing as a general reference to a promotion. It is an activation detail. If the terms say that a code is needed, enter it in the designated field before confirming the deposit. Do not assume that contacting support afterwards will make the transaction qualify.

This matters particularly when comparing a large advertised package with a smaller welcome bonus. A page may describe a 500% casino bonus code for UK players, but the percentage in the headline does not tell you whether the code applies to every stage of the offer or only to a particular deposit. The code and the offer terms work together.

I check four things before confirming:

• whether the code is compulsory or optional;
• whether it must be entered during the deposit;
• whether the promotion appears in the account before I proceed;
• whether the selected deposit method is accepted for that offer.

That last check is easy to skip. It is also where a tempting offer can become unavailable.

Automatic offers are not permission to stop reading

An automatically applied bonus removes the code field, not the conditions. You may still need to register as a new customer, opt in through the promotions area, or make a qualifying deposit. “Automatic” describes how the offer is attached; it does not mean every deposit receives it.

A specialist review states that some casino bonuses use a code at deposit while others are added automatically. I treat that as a description of changing offers, not as a permanent rule across the market. The only reliable answer is the current promotion page and its terms.

If the account shows no bonus after an automatic claim, I would avoid making another deposit to test it. Save the offer details, note the time of the transaction, and ask support to confirm the account status. More money does not make an unclear activation process clearer.

Online Casino Cashback Bonuses: Terms to Check

Check who is allowed to claim

Welcome offers are intended for new customers. That qualification can be affected by more than whether you have created a fresh username. An existing account, a previous registration, or a prior claim may matter under the operator’s rules.

A specialist review also describes welcome deals as restricted to one customer per household, with some deposit methods excluded. Because that condition can change from one promotion to another, I would read the specific terms rather than assume that a different person at the same address can claim the same offer.

Do not open duplicate accounts to get around a restriction. It can create an eligibility dispute and may affect the handling of any balance connected with the promotion. One account, one clear claim is the safer approach.

The deposit method can decide the result

The offer page should identify qualifying deposit methods. Some promotions exclude e-wallets, so a deposit that works perfectly for ordinary play may not activate the welcome bonus. That is why I check the method before entering a code, rather than after the money has arrived.

DO

• Check the deposit method before adding funds
• Verify the operator’s licence on the UKGC register

DON’T

• Use credit cards for gambling
• Use a wallet that permits credit-card funding

There is another UK-specific point: licensed casinos cannot accept credit cards for gambling, including credit-card funding routed through a money service business. Wallet payments funded by a credit card are also not accepted for gambling. If an offer page appears to suggest otherwise, stop and verify the arrangement with the operator.

For a UK-facing casino, I would also check that the operator holds a current UK Gambling Commission licence before depositing. The licence check does not activate a bonus, but it confirms that the offer belongs to a properly authorised operation serving British customers.

My quick pre-deposit check

Before I press the final button, I want the following settled:

1. I am eligible as a new customer.
2. The promotion is available to my account.
3. I know whether a promo code is required.
4. I have entered the code exactly as shown, if one is needed.
5. My chosen deposit method qualifies.
6. The offer is visible in the account or clearly marked as automatic.

That takes less time than arguing over a missing bonus later. A code is a small detail. It can still decide the whole claim.

Wagering on a 500% Bonus: The Numbers Behind the Small Print

A 500% deposit bonus can look enormous on the promotions page, but the useful number is not the percentage alone. It is the amount credited as bonus funds and the wagering multiple attached to that amount. The multiple tells you how much you must stake before the bonus balance can move towards withdrawal.

For customers using a site covered by the Great Britain licensing regime, wagering requirements on bonus funds cannot be higher than 10 times the bonus amount. That creates a clear ceiling for this part of the calculation. It does not mean every offer is automatically easy to clear, or that every part of a large welcome package is treated in the same way. It means the requirement applied to bonus funds cannot exceed that regulatory limit.

How the calculation works

Take a bonus of £20 with a 10x requirement. Multiply the bonus by ten:

£20 × 10 = £200

UK Online Casino Reload Bonuses: Terms and How They Work

You would therefore need to place £200 in total stakes before completing that wagering requirement. The £200 is the amount wagered across eligible play, not a fee charged separately from your balance. Even so, it is real money passing through games, and losses can occur while you work through the target.

I made the mistake of looking at the bonus figure first and the wagering line second. That reverses the order that matters. Start with the bonus funds, identify the applicable multiple, then calculate the total stakes. The headline percentage tells you how the bonus was built; the wagering calculation tells you how much play is attached to it.

The game can change the maths

Not every stake necessarily contributes at the same rate. Slots generally count in full towards wagering. Live tables and blackjack may contribute less, or may contribute nothing, depending on the offer rules. That means a £200 target cannot automatically be cleared by placing £200 on whichever game you prefer.

If a game contributes less than the full stake, more money may need to be wagered to generate the same qualifying progress. A game with no contribution does not help with the bonus requirement at all. This is why the eligible-games list matters alongside the headline multiple. The 500% label does not tell you how each category of game is counted.

Wagering Calculation

Example: £20 × 10 = £200 total stakes.

The same point applies to a promotion described alongside free spins. A deposit bonus and a spin incentive should not be treated as one simple pot for calculation purposes. Check which reward the wagering figure refers to and whether the game contribution applies to that reward. A “no wagering” phrase attached to one part of an offer does not, by itself, rewrite the conditions for bonus funds.

Track the progress, not just the target

A specialist review describes casinos as providing an account area where players can see the bonus balance and wagering progress. That is the practical place to check whether your stakes are being counted. I would look there after playing rather than trying to reconstruct every qualifying spin from memory.

The balance and progress display can also expose a mismatch between the games you played and the games the offer recognises. If the number barely moves after table play, the contribution rate may be lower than the slot rate, or the game may be excluded entirely.

That small display is worth more than the large banner. The banner sells the bonus; the account page shows the arithmetic.

No-Deposit Spins: Check the Clock and the Win Cap

“No-deposit spins” sounds like free play with nothing attached. I have learned to treat that phrase as the starting point, not the whole offer. The important details are often hidden in the clock, the permitted stake, and what happens to any winnings.

Daily spins may reset every 24 hours, according to a specialist review of these promotions. That does not necessarily mean unused spins accumulate. If you do not use that day’s allocation before the reset, it may disappear rather than join the next batch. I would check the exact reset time too. A 24-hour cycle can run from the moment the spins are credited, not from midnight.

Online Casino with a 400% Bonus: Terms Explained

The stake is another catch. A specialist review puts the commonly stated spin-value limits in the range of 10p to 25p per spin. That is an offer condition, not an invitation to increase the stake after a win. If the terms set a fixed value, playing at a different stake may cancel eligibility for the promotion or leave the spin outside the qualifying rules.

The biggest misunderstanding is treating the result as cash. Daily-spin winnings may be placed in the bonus balance instead. In that case, the win is not ready to withdraw simply because the reels produced it. A specialist review describes wagering requirements of 20x to 65x the bonus amount for this type of promotion. The exact figure belongs to the individual terms, so I would look for it before starting the spins.

That also changes how you judge a small win. If a spin produces a bonus balance, the required playthrough applies to that credited amount, not just to the original free spin. A modest-looking win can therefore become a much longer task than expected. Keep an eye on the account’s bonus display rather than assuming the cash balance tells the full story.

Then there is the win cap. A specialist review places reported maximum winnings from daily spins between £20 and £100. If the promotion has such a ceiling, a larger result may still be restricted to the stated maximum. It is a hard limit, not a target you can unlock by continuing to play.

Warning Winnings from daily spins may be subject to a win cap, typically between £20 and £100.

Finally, the winnings can expire separately from the spins themselves. The same type of review describes expiry periods ranging from 24 hours to 7 days for spin winnings. I would record the credit time and deadline immediately. Free can be very brief.

When a 500% Bonus Can Become Real Money

A 500% casino bonus can look like money in your account, but that does not make it cash. I made that mistake once: I saw the balance rise and mentally spent it before checking what kind of funds I was looking at. A bonus balance is promotional credit. It can be used under the offer’s conditions, but it is not automatically available for withdrawal.

The important distinction is between the bonus itself and winnings produced while using it. Even when the balance shows a clear cash value, the casino may keep the bonus funds restricted until the offer’s conditions have been met. Trying to withdraw too early can lead to the bonus being removed, with the available amount changing as a result. That attractive figure is not the same as cleared money.

I now treat a large welcome bonus as a temporary playing balance rather than income. The amount that matters is the sum left after the offer has been completed and the casino has accepted the withdrawal request. Until then, the balance can be useful for play, but it should not be counted towards rent, bills, or anything else outside the casino.

There is one important contrast. A genuinely wager-free offer pays winnings as cash without playthrough, according to a specialist review. That is a different arrangement from bonus credit: the winnings are not held back for another round of play under a wagering condition. However, the label needs checking in the actual terms, because “wager-free” applies to the stated offer, not automatically to every bonus or spin attached to an account.

Online Casino with 100% Bonus: What to Check

My rule is simple: promotional balance is not spendable money, and a withdrawal-ready balance is not confirmed until the casino processes it. Read it that way, and the headline becomes less seductive. Much less.

A Deposit Match Is Not the Same as a 500% Match

A deposit match is a straightforward idea: the casino adds a percentage of a qualifying deposit as bonus funds. The percentage applies to the deposit, while the advertised maximum limits how much bonus can be credited. It does not mean that your deposit becomes five times larger in cash.

One example reported in a specialist review is Casumo’s 50% deposit match, capped at £100. That is a different proposition from a 500% casino deposit match in the UK. The Casumo figure describes one match rate and one ceiling; it does not describe a five-stage package or suggest that the account receives five times the deposit.

I have made the mistake of reading the large percentage first and the word “bonus” second. That is how a simple deposit match starts looking like spendable money. It is not. The added amount is bonus funds, and the offer’s own conditions decide how it can be used and whether it can later support a withdrawal.

The distinction also matters when comparing welcome offers. A specialist review lists several different arrangements: LuckyMate is paired with a £10 bonus and 50 free spins, while BetWright Casino and Quickbet are each shown with 100 free spins. BetMGM Casino is listed with 200 free spins. Those are not evidence of a 500% deposit match; they are separate welcome-offer figures. Different reward types, different mechanics.

So, when you see a claim about a 500% bonus, first ask whether it describes a single deposit match or a package built from several stages. A listed 50% match up to £100 should be read exactly as written, not mentally upgraded into a 500% offer.

Small wording. Big difference.

“No Wagering” Free Spins: Check What Happens to the Winnings

The phrase “no wagering” sounds wonderfully clean. I have learned not to stop reading there. The important question is not only whether the spins cost nothing, but what happens to anything they produce.

A genuinely wager-free offer means the winnings are credited as cash. There is no playthrough attached before you can request a withdrawal. That is the straightforward version: spin, win, and the resulting money is treated as cash rather than being moved into a bonus balance with another condition attached.

A specialist review describes wager-free offers in those terms, but that should not be confused with every free-spin promotion using similar language. Some offers remove wagering from the spins themselves while still placing a requirement on the winnings. In that case, the free spins may be granted without a deposit or without a separate stake, yet the money won from them cannot be withdrawn immediately.

That distinction matters when you see a large package described as a 500% bonus with free spins and “no wagering”. The phrase may relate only to one part of the promotion. The deposit bonus, the spins, and the winnings from those spins can each have their own treatment. Advertising compresses all of that into a few attractive words.

I once read “no wagering” and mentally counted the winnings as cash before checking the conditions. That was premature. Look for the exact wording around spin winnings, cash balance, withdrawal eligibility and any playthrough attached after the result is credited.

Online Casino with a 200% Bonus: What to Check

Another specialist review notes that free-spin winnings can carry wagering requirements before withdrawal. So the useful test is simple: does the offer say the winnings are cashable immediately, or does it say they become bonus funds first? If the latter applies, “no wagering” has not removed every condition.

Small wording difference. Big consequence.

The Terms That Change a Bonus’s Actual Value

The headline is only the front of the offer. The useful part is buried in the terms and conditions, where a 500% casino bonus for UK players can become far less generous than it first sounds.

I have made the mistake of looking only at the percentage and the maximum bonus. That skips the questions that decide whether the offer suits you at all:

• Eligibility: welcome bonuses are intended for new customers, and the operator may limit one offer to one person or household.
• Qualifying deposit: not every deposit necessarily triggers the bonus. The terms may specify which deposit qualifies and whether the offer must be selected before paying in.
• Game contribution: different games can count differently towards the conditions. A slot may contribute fully, while table games or live dealer titles can contribute only partly or not at all.
• Expiry: bonus funds and free spins do not remain available indefinitely. A specialist review identifies time limits between 7 and 30 days, but the operator’s current terms are the ones that decide your deadline.
• Withdrawal conditions: the balance shown in your account is not automatically cash. The rules may set conditions on the bonus, its winnings, or the amount that can be withdrawn.

That last point is where advertising language does the most work. “500%” describes the promotional calculation, not the amount you can simply transfer to your bank account. The real value depends on the reward offered, your eligibility, the qualifying deposit, game contribution, expiry and withdrawal rules. That assessment comes from a specialist review, so I would treat it as a checklist rather than a permanent rule for every casino.

Before depositing, I read the full welcome-bonus terms, including the small sections below the main banner. If the deadline or withdrawal wording is unclear, I leave the offer alone. Five minutes of checking beats discovering the catch after the money is already committed.
