Best Discount Grocery App UK (2026): Cut Your Supermarket Bill
Food shopping is one of those costs that quietly creeps up. You don’t change where you shop, you don’t buy more than usual, yet somehow the bill is £20 higher than it was a year ago.
The good news is that the best discount grocery apps can cut a noticeable chunk off your supermarket spend. Some give instant cashback at the till, others refund items after you shop, and a few even offer free food if you’re willing to be flexible.
I use several of these apps every week. Some are better than others, and rates change all the time, but right now, these are the apps that genuinely reduce grocery costs in the UK.

EverUp
⭐⭐⭐⭐⭐ 4.6/5
Best for: highest supermarket cashback right now
If someone asked me today for the best discount grocery app, EverUp would be the first one I’d mention.
I’ve used JamDoughnut for years, but lately EverUp has been offering better cashback rates on supermarkets — enough that it’s now the app I check first before a food shop. It works by giving cashback when you buy supermarket gift cards or shop via linked retailers, with Tesco, Asda and Sainsbury’s regularly included.
Rates change, but when EverUp is on form, it’s one of the easiest ways to shave a few pounds off your weekly shop without changing where or how you buy food.
Why EverUp works
✅ Often higher grocery cashback than JamDoughnut
✅ Covers major UK supermarkets
✅ Cashback on your full shop, not selected items
✅ App is quick to use once set up
Where it falls short
❌ Cashback rates can fluctuate
❌ App leans into prize draws (not everyone’s thing)
❌ Not every supermarket is always available

JamDoughnut
⭐⭐⭐⭐⭐ 4.5/5
Best for: steady, no-nonsense grocery cashback
JamDoughnut is still one of the most reliable discount grocery apps I use — even if EverUp has been edging ahead on rates lately.
It works by letting you buy digital supermarket gift cards through the app and use them to pay in-store or online. Cashback tracks instantly, there’s no receipt uploading, and it covers your entire shop, not just selected items.
I use JamDoughnut when I want predictable savings without checking prize draws or fluctuating rates. It’s simple, quick, and very hard to mess up — which is exactly why it remains a permanent fixture on my phone.
Why JamDoughnut works
✅ Consistent cashback at major supermarkets
✅ No receipt scanning or waiting for approval
✅ Covers your full grocery spend
✅ Cashback tracks instantly
Where it falls short
❌ Rates are sometimes beaten by EverUp
❌ No extra rewards or bonuses
❌ Slightly lower peaks when cashback is hot elsewhere

Shopmium
Best for free branded groceries
Shopmium lets you claim cashback on specific supermarket items by uploading a photo of your receipt. Some offers are 50% cashback, others are 100%, meaning the item is completely free.
It’s not designed for your full weekly shop, but it’s excellent for snacks, drinks and cupboard fillers when the offers line up.
- Cashback paid via PayPal
- Works at major UK supermarkets
- Offers change weekly
Best for: Free or heavily discounted groceries
Realistic saving: £5–£20 per month

GreenJinn
Best for discounted premium and branded food
GreenJinn works in a similar way to Shopmium but often focuses on premium brands and higher-value products, including health foods and meat alternatives.
You activate offers before shopping, upload your receipt afterwards, and receive cashback once approved.
- Strong on premium brands
- Regular 50%+ cashback offers
- Occasional free items
Best for: Discounted branded groceries
Realistic saving: £5–£15 per month
Olio
Best for free food locally
Olio helps reduce food waste by allowing people and businesses to give away surplus food for free.
Items are collected locally, often from supermarkets, cafés or neighbours. You won’t rely on it for a full shop, but when it works, the value is unbeatable.
- Completely free
- Local collections only
- Availability varies by area
Best for: Free food
Realistic saving: £10–£30 per month (very variable)
Too Good To Go
Best for: cheap food and surprise bags
(Full Too Good To Go review →)
Too Good To Go is best when you fancy a bargain and don’t mind a surprise. You pay a small amount for a Magic Bag of surplus food from supermarkets, bakeries or cafés and collect at a set time. Great for cheap treats — not ideal if you’re picky or meal planning.
- Big discounts on surplus food
- Fixed collection windows
- Contents vary every time
Best for: Cheap groceries and treats
Realistic saving: £3–£15 per month
How much can you realistically save with grocery apps?
Used casually: £10–£20 per month
Used properly: £30+ per month
My usual setup:
- EverUp or JamDoughnut for the main shop
- Shopmium or GreenJinn checked beforehand
- Olio or Too Good To Go when convenient
It doesn’t change where I shop — it just quietly reduces the bill.
Final verdict: what is the best discount grocery app?
Right now, EverUp is the best discount grocery app if you want the highest supermarket cashback.
JamDoughnut is the best backup when rates are steadier or a retailer isn’t available.
The real savings come from stacking apps, not picking just one.
That’s how you stop grocery costs creeping up — without changing how you shop.

Frequently asked questions about discount grocery apps
What is the best discount grocery app in the UK?
Right now, EverUp is the best discount grocery app if your goal is highest supermarket cashback. Rates change regularly, which is why it’s smart to also keep JamDoughnut as a backup for steady, predictable savings.
Can grocery apps really save you money?
Yes — but only if you use them properly. One app on its own might save a few pounds a month. Stacking two or three apps (cashback + receipt apps + surplus food apps) is how you realistically save £30+ per month on groceries.
Are discount grocery apps safe to use?
The apps listed here are well-established in the UK and don’t require access to your bank account unless you choose to link one. Receipt cashback apps only need photos of receipts, while gift-card apps act as a payment method rather than accessing your spending directly.
Do I have to switch supermarkets to use these apps?
No. That’s the main advantage. Most discount grocery apps work with Tesco, Sainsbury’s, Asda, Morrisons and Co-op, so you can keep shopping where you already do.
Which app is best for free food?
For genuinely free food, Olio is the standout. For free branded items, Shopmium and GreenJinn regularly offer 100% cashback on selected products.
Do these apps affect prices in-store?
No. You pay the normal shelf price. Any savings come after checkout via cashback or discounted collections.
