How to Save Over £250 a Year Shopping at Sainsbury’s
Sainsbury’s isn’t the cheapest supermarket in the UK. Aldi and Lidl exist, and yes, I know I could shave more off my bill by shopping around. But Sainsbury’s offers good quality, a wide range of products and, most importantly for me, convenience.
And convenience matters.
So here are a few simple ways I cut my Sainsbury’s bill every week.
I’m not a hardcore frugal blogger. I don’t want to visit three supermarkets in one week just to save a few quid. I also worked for Sainsbury’s for four years, so there’s probably a bit of loyalty in there too. And if all else fails, I’ve got two kidneys.
That said, if you’re looking for legit ways to save money at Sainsbury’s without switching supermarkets, these are the exact methods I use every week. No extreme couponing. No spreadsheets. Just small habits that quietly add up to over £250 per year.
| Method | Typical saving | Effort level | Best for |
|---|---|---|---|
| Gift cards (EverUp, JamDoughnut, Sprive) | 3%–5% per shop | Low (1–2 minutes) | Maximising savings without changing where you shop |
| Cashback sites (TopCashback, Quidco, Rakuten) | 1%–4% when available | Very low | Occasional bonus savings |
| Chase debit card | 2% (up to £20/month) | None | Set-and-forget simplicity |
Buy Sainsbury’s gift cards for instant cashback
This is where most of my savings come from.
Sainsbury’s used to limit how much you could pay with gift cards. That restriction is gone. You can now cover your entire shop using gift cards, which opens the door to easy cashback.
I rotate between a few apps depending on which offers the best rate.
Everup
EverUp pays me cashback when I buy Sainsbury’s gift cards. That cashback can then be used towards more gift cards or withdrawn. Rates typically sit between 3% and 5%, which adds up fast over a year.
JamDoughnut
JamDoughnut works slightly differently. Instead of cashback, you earn points, which you can convert to cash or use for more gift cards. Rates are usually a bit lower than EverUp, but the flexibility is good.
Use code O8ZG and you’ll get 300 points (£3) after your first purchase.
Sprive
Sprive also offers cashback on gift cards, but there’s a catch. Any cashback earned can only be put towards your mortgage. That won’t suit everyone, but the rates can be higher, so I do use it from time to time.
Use code INRWFKGS and you’ll get a £5 mortgage bonus.
Sainsbury’s cashback: when it’s worth using
Cashback sites are simple, but you need to be realistic. Cashback on Sainsbury’s purchases comes and goes.
The three worth having are TopCashback, Quidco and Rakuten. At least one of them usually has an offer running.
The process is straightforward:
Open a cashback account
Search for Sainsbury’s
Click through to the website
Shop as normal
Tracking usually appears within hours and becomes payable in a few weeks. It’s not massive money, but it stacks nicely with gift cards when available. I’ve covered this properly in my guide to the best cashback sites.
Recently, I have been using TopCashback, which offers £1.10 back on each shop. Not massive, but over £55 per year.
Receipt scanning
This one still surprises people.
There are companies that will pay you just for scanning your receipts. No surveys. No effort. You’re literally getting paid for shopping receipts you already have.
I currently use SnapMyEats, Shoppix and Clear! and between them, I make over £100 per year.
It takes seconds and runs quietly in the background. If you’re not doing this, you’re leaving money on the table. Take a look at my post on the best receipt-scanning apps to find out more.
Chase bank account
This is worth considering if you can’t be bothered to buy gift cards. The Chase debit card will give you 2% cashback on your shopping, up to £20 per month. It’s not as good as a gift card, but it’s a slightly simpler option.
There are a couple of conditions for the cashback, which you can learn more about in this review of the Chase account.
Nectar Prices
I can’t write about saving money at Sainsbury’s without mentioning Nectar Prices and the app. I’m sure most people are aware of them, but here’s a gentle reminder.
Check your Nectar account or the app each week for discounts and bonus points. Some of these are exclusive to you and are generally for products you usually buy. All you need to do is add them to your offers with a click of a button. New deals are added every Friday.
For full details, check out my post about Nectar Prices.
How much do I really save?
Excluding Nectar Prices, I save around £4–£5 per week on average. Over a year, that’s comfortably £250+. Some weeks it’s more, some weeks less, but even £1 per week is £52 you didn’t have before.
None of this requires switching supermarkets or changing what you buy. You’re just paying smarter.
