How does supermarket cashback work?
If you've never used a supermarket cashback app before, it's worth starting with the basics. A supermarket cashback app is a free phone app that pays you a small amount of money back on certain branded products you buy on your normal grocery shop. Rather than giving you a discount at the till, it works after you've paid: you buy a product that's listed in the app, submit a photo of your receipt as proof, and the app pays a set amount back to you, which you can later withdraw to your bank or PayPal.
The products on offer are usually well-known brands running a short promotion, and the amount you get back ranges from a few pence to, in some cases, the full price of the item. CheckoutSmart is one of the best-known of these apps in the UK, sitting alongside names such as GreenJinn and Shopmium. This review explains what it is, how it works, what's good and less good about it, and how I've earned £496.75 from it over the years, as checked in my account on the 4th of August, 2026.
The most important thing to note is that CheckoutSmart doesn't give you money off at the till, and it isn't a voucher or a coupon. You pay the full price in the shop as normal, then claim your money back afterwards by uploading a photo of your receipt through the app. Once the receipt is checked and approved, the cashback is added to your CheckoutSmart account, ready to withdraw. The cashback comes back to you after you shop, rather than as a discount at the point of sale, and that's important to understand.
CheckoutSmart earns its place as a money-saving tool because the savings it offers are real but modest, and as a result, the savings accumulate gradually rather than forming part of a weekly budget saving you rely on. My own total of £496.75 has come from checking the app before I shop and then claiming on products I was buying anyway, or on products I could switch to in place of a similar item I would have bought regardless. That switch turns into a cashback saving without my spending any more than I intended.
The reason that distinction matters is that there's little point in buying a product purely for the cashback if you may not actually use it. In that case, the cashback doesn't save you anything; it adds an extra cost. The savings only count when they come off spending you were going to make anyway.
How does the CheckoutSmart app work?
CheckoutSmart is a UK supermarket cashback app that lists specific branded products you can earn money back on, sold in shops you already use. Those shops range from the big supermarkets through to convenience stores, pharmacies, fuel stations, and even food delivery apps. You browse the offers, buy the ones that suit you, and claim your cashback by scanning the receipt.
The amount you get back varies from product to product. Sometimes it's a small saving, a few pence towards an item, and sometimes the cashback covers the entire price, which makes the product effectively free. There's no cost to using the app itself; it's free to download on both iPhone and Android, and you only ever pay the normal shop price for the products, getting your cashback back afterwards.
These offers exist for a commercial reason, which also explains why they come and go. Brands use cashback to get people to try their products, so rather than cutting the shelf price for everyone, a brand pays for cashback on a selected item for a limited time, in the hope that you'll buy it, like it, and keep buying it later at full price.
It's worth being clear that the cost is funded by the product's manufacturer or supplier, not the shop; the supermarket simply takes your full payment at the till, and the manufacturer covers the cashback separately through the app. For you, that means a chance to cut your shopping bill or try something new without paying full price, while the manufacturer treats it as a marketing cost, which is why the offers rotate week to week rather than staying put.
It helps to think of this as the modern version of couponing. Before the technology moved on, brands would print coupons in newspapers and magazines, produce their own coupon booklets, or pay to be included in a supermarket's booklet, and you'd cut out the coupon, take it to the till, and get your discount that way. A supermarket cashback app does the same job digitally, replacing the paper coupon with a listed offer and a scanned receipt.
The digital approach gives brands far more control than print ever did. They can add new deals, change them, and rotate them quickly, and they can cap how many people claim an offer. Rather than risk giving away a million free chocolate bars, a brand can set a limit of, say, ten thousand, and once those have been claimed, the offer simply closes, which makes the whole thing more cost-effective and far easier to manage.
That capping has a practical consequence worth being aware of across supermarket cashback apps generally. Because the number of claims on an offer can be limited, a deal you can see in the morning may reach its maximum redemptions and close later the same day. If you buy a product expecting to claim, then leave uploading your receipt until the evening, you can find the offer has already gone, and you're left paying full price. The safest approach is to claim as soon as you can after buying rather than leaving it for later.
It also lets brands target their spending more precisely. Using the data from supermarket loyalty cards, along with the likes and dislikes you enter in the app, they can put the right products in front of the people most likely to want them. That reduces the money wasted on shoppers who'd never buy the product anyway, and puts the offer in front of those more likely to try it and keep buying it, so a cashback offer is essentially a well-controlled, closely targeted advert that the brand pays for.
How is CheckoutSmart different from apps like JamDoughnut?
The word cashback is used for two quite different types of apps and websites. General cashback apps and sites such as TopCashback or JamDoughnut give you a percentage back on your whole spend; you shop as normal, spend £50, and receive a small proportion of that total back afterwards, whatever you bought.
Supermarket cashback apps like CheckoutSmart work the other way round. Instead of paying you back on everything, they pay a set amount on specific listed products, usually branded items, with the cashback amount set per product. It sits in the same family as other supermarket cashback apps you might have heard of, such as GreenJinn and Shopmium, all of which work on the same buy-it-then-scan-your-receipt basis.
There's no need to choose between the two types. You can use a general cashback app and a supermarket cashback app on the same shop, so the savings stack rather than cancel out. If you're shopping online, you might click through a cashback site like TopCashback or Rakuten first, or pay in-store with a cashback gift card from an app like JamDoughnut, earning cashback on the whole spend, and then separately claim on CheckoutSmart for any listed products in that same shop. Used together, that's cashback on the overall purchase plus extra cashback on specific items within it.
How does the CheckoutSmart app work, step by step?
Using CheckoutSmart follows the same pattern every time, and it can be broken down into four steps, done in order.
Browse the offers in the app, each showing the product, the shops where it's valid, and how much cashback you'll get
Buy the exact product listed on your normal shop, matching any conditions like the size, flavour, or pack type
Scan or photograph your receipt and submit the claim through the app
Wait for the claim to be approved, at which point the cashback lands in your CheckoutSmart balance
Once your balance is large enough, you withdraw it to your bank or PayPal, which is covered further down. The habit that makes the difference is checking the app before you write your shopping list rather than after you've already bought everything, so the cashback fits around a shop you were doing anyway rather than being missed.
What are standard offers and the RRP scheme?
CheckoutSmart splits its deals into two main types, and a newcomer only needs the first. Standard offers are the everyday cashback deals available to all users, and they make up the bulk of the app. You buy the product, scan your receipt, and receive your cashback once it's approved, with no additional steps beyond following the offer's conditions.
The second type is the Review Reward Programme, usually shortened to RRP, and it's an invite-only add-on to the app. Not everyone gets it; there's no way to apply, and while some users are selected for access over time, there's no guarantee you ever will be. The RRP deals are higher value than the standard ones, with far more products that end up completely free after cashback, which is the main draw of getting access.
The trade-off is that reviews are required rather than optional. Once you've bought and tried an RRP product, you're expected to leave a written review of it, and if you stop leaving reviews you're removed from the scheme. Leaving reviews where you can, even on standard offers, can also improve your chances of being invited into RRP in the first place, so it's a habit worth building if the higher-value deals appeal to you.
RRP offers are online only, so you won't find them on in-store products. They apply to online food shops through sites such as, but not limited to, Tesco.com, Sainsbury's.com, Morrisons.com, and Ocado. You buy the products as part of your online order, then claim by uploading your online receipt through the app in the usual way, and the cashback follows once it's approved.
The reviews themselves are handled through the CheckoutSmart app, which keeps the process manageable. In practice, a review is often posted on the retailer's own website rather than inside the app, and you may sometimes be asked to review a product on other retailers' sites too, not only the one you bought from.
As an example, you might buy an item at Tesco but be asked to leave a review on the Sainsbury's and Asda sites as well, because the review is tied to the product rather than the shop. You don't have to visit each site separately, as the app walks you through it, but it does need doing, so RRP is more labour-intensive than standard offers in exchange for the larger number of free products.
If you do have RRP access, the app shows three tabs along the top. The first, Offers, holds the standard deals available to everyone. The second, RRP Offers, lists the higher-value RRP deals and can be filtered by supermarket, so you can see which products are available and what the discounts are at each shop. The third, RRP Requests, is where you claim your cashback on RRP products you've bought and deal with the associated reviews.
To give a sense of the scale, the Tesco RRP offers on the 4th of August 2026 ran to 22 products, of which 17 were completely free after cashback. The remaining five carried cashback of £2.50, £3, or £3.50, which works out at least half off and often more. In principle, you could order all of them in a single online shop, which could take you past the minimum for delivery, and then claim most of the cost back, filling a large part of a shop with products that cost you little or nothing.
Anyone new to CheckoutSmart can set all of this aside to begin with, because the standard offers provide the full cashback experience without any reviewing at all. RRP is best thought of as a higher-effort, higher-reward tier rather than something you need on day one. It's there to grow into if you're invited, once you're comfortable with how the standard side of the app works.
How do CheckoutSmart payouts and fees work?
CheckoutSmart pays out from a minimum balance of £5, and you can withdraw your money to either PayPal or your bank account. There is one fee to be aware of: withdrawals of £19.99 or less carry a 5% transfer fee, while withdrawals of £20 or more are free of charge, which is why it can be worth letting a balance build past £20 before cashing out.
It's also worth setting expectations on timing, because this is not instant money. Withdrawals are processed at set times and usually reach you within around two weeks, so cashback returns steadily rather than the moment you claim. The app is best understood as a gradual saver rather than a source of immediate returns.
Which shops can you use CheckoutSmart with?
CheckoutSmart works across a wide range of shops, so a typical weekly supermarket is likely to be covered. The major supermarkets include Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl, Waitrose, Iceland, Ocado, and Marks and Spencer, and beyond the big grocers, offers regularly appear at:
High street and health shops such as Boots, Superdrug, Holland & Barrett, LloydsPharmacy, WHSmith, Pets at Home, B&M, Poundland, and The Range
Fuel stations and travel stops such as BP, Shell, Spar, and Moto
Convenience chains including Londis, Premier, Budgens, One Stop, and Nisa
Online retailers and food delivery apps including Amazon, Deliveroo, Just Eat, Uber Eats, GoPuff, and Wetherspoons
Not every shop has offers running all the time, and the deals rotate depending on which brands are active, which is exactly why a quick look at the app before you shop makes such a difference to what you get back.
How do you actually save money with CheckoutSmart?
The principle to keep in mind is that CheckoutSmart saves you money when it lowers the cost of things you were already going to buy, and it costs you money when it prompts you to buy things you weren't. If a product was on your list anyway and there's cashback on it, that's a genuine saving; if you buy it only because of the cashback, you can end up spending more overall than you get back.
A useful test for any offer is to ask whether you'd still be content to buy the product if the cashback failed to track. If the answer is no, it's usually best to leave it. The largest savings tend to come when cashback lines up with supermarket loyalty pricing, such as Clubcard or Nectar deals, because when those overlap, a full-price item can end up costing very little, or occasionally nothing at all.
What are the downsides of CheckoutSmart?
No app is perfect, so it's fair to be clear about the drawbacks before you download it. You pay full price upfront and wait for the cashback, rather than saving at the till, which won't suit everyone. The offers also change from week to week, so there won't always be something you actually want, and the small withdrawals under £20 carry that 5% fee.
The RRP side has become a little more involved too, now that reviews for some shops are left on the retailer's own website rather than in the app, so it suits those willing to take a few extra steps in return for the higher-value deals. These are not major drawbacks, but they explain why CheckoutSmart is a steady background saver rather than a quick or effortless one, and it's better to know that before you start.
Is CheckoutSmart worth using if you're new to saving money?
If you're just starting to be more careful with your grocery spending, CheckoutSmart is an easy first step, because it doesn't ask you to change where you shop or overhaul your routine. It simply gives you the option to get a little money back on things you were probably buying anyway, or to swap one product for a similar one that has cashback attached. Some weeks the offers will line up nicely with your shop, and other weeks they won't suit you at all, which is just the nature of these apps.
Used steadily and sensibly, it becomes a useful little money-saving tool that trims your shopping costs over time, and my running total of £496.75 is the result of exactly that low-effort, long-term approach rather than any special trick. If you'd like to compare it with the two closest alternatives before you decide, our GreenJinn and Shopmium reviews cover apps that work in much the same way, and trying more than one is a good way to catch more of the offers that suit you.
Frequently asked questions
What is CheckoutSmart?
CheckoutSmart is a UK supermarket cashback app that pays you money back when you buy specific branded products and upload a photo of your receipt. You shop as normal, submit the receipt, and the cashback lands in your account once the claim is approved. Some offers give a few pence back, while others cover the full price of the item.
How does CheckoutSmart cashback work?
You pick an offer in the app, buy that exact product on your normal shop, then scan your receipt to claim. The cashback is added to your CheckoutSmart balance once the claim is approved, and you withdraw it to PayPal or your bank when it reaches the minimum. The money comes back after you shop, not at the till.
Is CheckoutSmart legit?
Yes. CheckoutSmart is a long-running UK cashback app that pays real cashback once claims are approved. I've personally withdrawn £496.75 over the years I've used it, so the payments are genuine when you follow the offer rules.
Is CheckoutSmart free?
Yes, the app is free to download and use on iOS and Android. The only cost to be aware of is a 5% transfer fee on withdrawals of £19.99 or less; withdrawals of £20 or more are fee-free. The minimum you can withdraw is £5.
How is CheckoutSmart different from apps like TopCashback?
Apps like TopCashback give you a small percentage back on your whole spend, whereas CheckoutSmart pays a set amount on specific listed products. You claim on individual items rather than the full basket, and you can happily use both types of app on the same shop so the savings stack.
What is the CheckoutSmart RRP scheme?
RRP is the Review Reward Programme, an invite-only feature that offers selected users higher-value deals in return for reviewing the product. You can't apply for it, and if you never get access, you lose nothing, because the standard offers work exactly the same without it.
Is there a CheckoutSmart referral code?
No. Unlike Shopmium, CheckoutSmart doesn't run a referral scheme, so there's no promo code to enter. There's a promo code box in the app, which suggests it could change, but nothing is active at the moment.
