How to save money at the supermarket with reward cards and apps
Your weekly food shop doesn’t have to drain your bank account. With the right reward cards and apps, you can save hundreds of pounds off your annual food shop without changing what you buy. Whether you’re a Tesco regular or a Lidl shopper, there are savings waiting to be claimed.
Let’s look at the best ways to use supermarket loyalty schemes, cashback apps, and receipt scanning tools to keep more money in your pocket.
Why supermarket reward cards actually matter
Supermarket loyalty cards have become essential shopping tools. Around 76% of UK consumers now use at least one scheme, according to Mintel. That’s no surprise when you look at the numbers: Tesco claims Clubcard holders save up to £375 a year, while Sainsbury’s says Nectar members can save over £450.
The Competition and Markets Authority reviewed 50,000 products with loyalty pricing and found that 92% offered genuine savings against standard prices. Translation? These cards deliver real discounts, not marketing tricks.
But here’s the catch: not using a card often means paying more for the same items. That Diet Coke might cost you £8 without a card and £5 with one. Same product, different price tag.
Personally, I find this infuriating, but what can we do? As a result, it feels we are forced to get all the apps and cards, so here is a bit of a summary of how each works.
The major UK supermarket loyalty schemes
Tesco Clubcard
How it works: You earn one point for every £1 spent. Each point equals 1p when converted to vouchers, which arrive quarterly. You can spend these vouchers in Tesco or exchange them for double their value with reward partners like Pizza Express.
The real savings: Clubcard Prices offer instant discounts on 10,000+ items weekly. That’s where the big savings happen. The meal deal costs £3.85 with a card versus £4.25 without one.
Sign up: Register at tesco.com/clubcard or pick up a card in store. Download the Tesco app to access digital coupons.
Sainsbury’s Nectar
How it works: Earn one point per £1 spent. Points are worth 0.5p each and can be spent in blocks of 500 (£2.50). You can collect and spend points with 500+ partners, including Argos and British Airways.
The real savings: Nectar Prices give members-only discounts on thousands of products. You also get “Your Nectar Prices” – up to 10 personalised weekly deals based on your shopping habits.
Sign up: Visit nectar.sainsburys.co.uk or ask for a card at the till.
Lidl Plus App
How it works: App-only scheme with weekly rotating coupons and personalised offers. Spend £10 in a month and unlock a free bakery item. Spend £250 and get 10% off your next shop (up to £20 discount).
The real savings: Weekly deals refresh every Thursday with discounts like 27% off Rubicon mango juice. Partner benefits include £65 off Jet2holidays bookings.
Sign up: Download the Lidl Plus app. No physical card available.
Asda Rewards
How it works: Complete “missions” (like spending £5 on ready meals) to earn pounds, not points. Money goes into your “Cashpot” and converts to vouchers once you’ve built up enough.
The real savings: Some active users earn hundreds yearly by completing all missions and using coupons. Money can be spent on your shopping.
Sign up: Download the Asda Rewards app.
Morrisons More Card
How it works: Earn five points per product purchased. When you reach 5,000 points, convert them to a £5 voucher. Look for “More Card Prices” and “Points Boosters” for extra savings.
The real savings: More Card Prices offers members-only discounts on hundreds of items weekly. Points expire after 12 months, so use them regularly.
Sign up: Register at more.morrisons.com or request a card in-store.

Cashback websites: TopCashback and Quidco
Cashback sites pay you for shopping online at retailers you already use. They earn commission from stores and share it with you.
TopCashback
Offers cashback at 5,000+ retailers. Free membership gives you access to all deals. Premium membership (£5/year) adds extra perks like higher cashback rates.
How to use it:
- Visit TopCashback and search for your chosen retailer
- Click through to the retailer’s website
- Shop normally
- Cashback appears in your account (usually within 3-6 months)
- Withdraw once you hit £10 minimum
Popular offers include up to 16.5% at Currys and up to 6.6% at Argos. TopCashback’s supermarket loyalty guide provides detailed breakdowns of each scheme.
Quidco
Works similarly to TopCashback with 5,000+ retailers. Basic membership is free. Premium costs £1/month (deducted from your cashback only, never from your bank).
Quidco’s cashback system tracks purchases through cookies. Premium members get ad-free browsing, up to 10% cashback top-ups, and up to 20% payout bonuses when withdrawing as gift cards.
Top tip: Compare rates between TopCashback and Quidco before each purchase. Rates vary and one often beats the other.
Receipt scanning apps that pay you back
These apps give you cashback for buying specific products. Simply scan your receipt after shopping.
Shopmium
Offers full or partial refunds on featured products. Buy the item, photograph your receipt, scan the barcode, and get money back within 48 hours.
How it works:
- Browse offers in the Shopmium app
- Buy qualifying products at any UK supermarket
- Snap a photo of your receipt
- Scan product barcodes
- Receive cashback once you reach £10
Withdrawal options include bank transfer, PayPal, or gift cards with bonus percentages.
Other receipt apps worth trying
GreenJinn: Focuses on eco-friendly products with cashback offers.
CheckoutSmart: Similar to Shopmium with weekly rotating offers.
These apps work alongside loyalty cards, so you can double-dip on savings.
Smart strategies to maximise your savings
Stack your discounts
Use multiple savings methods on the same purchase:
- Scan your loyalty card for member prices
- Check TopCashback or Quidco for online orders
- Upload receipts to scanning apps for product-specific cashback
Activate offers before shopping
Most schemes require you to “clip” or activate offers in the app before purchase. Spend five minutes reviewing available deals before heading to the shop.
Compare loyalty prices across stores
Which? research shows that loyalty cards don’t always guarantee the lowest prices. Aldi often beats Tesco Clubcard prices, while Asda regularly undercuts Sainsbury’s Nectar deals. Don’t assume your card automatically gives you the best value.
Watch for “price matching” tricks
Some Clubcard and Nectar prices simply match competitors’ regular prices rather than offering genuine discounts. Always compare unit prices (price per 100g or per litre) to spot true bargains.
Set price alerts
Use apps like Trolley.co.uk to track prices across multiple supermarkets. You’ll know when items hit their lowest price point.
Only buy what you need
Loyalty pricing tempts you to stock up, but bulk buying backfires if food goes to waste. Stick to your shopping list and resist “offers” on items you wouldn’t normally purchase.
The downsides you should know about
Your data is valuable
The Information Commissioner’s Office warns that loyalty cards collect extensive data about your shopping habits. Supermarkets know where you shop, how much you spend, and what you buy, from snacks to pharmacy products.
This data can be used for targeted advertising. While UK law requires consent for data sharing, always read privacy policies carefully.
Age and digital barriers
Many schemes require smartphones and email addresses. Which? notes that Lidl Plus is app-only, excluding customers without smartphones or those who prefer not to go digital. Some schemes also have minimum age requirements.
The illusion of free money
Reward points aren’t “free money” – you’re earning back a tiny percentage of what you’ve already spent. Don’t let points pressure you into unnecessary purchases.
Points can expire
Morrisons More points expire after 12 months. Tesco Clubcard vouchers expire after two years. Track expiry dates for any points or vouchers for your loyalty cards to avoid losing rewards.
Frequently asked questions
Do I really need multiple loyalty cards?
Yes, if you shop at different stores regularly. Each card only works at its own chain, so having several ensures you never pay full price. Around 60% of UK shoppers now use four or more loyalty schemes.
Can I use cashback sites with loyalty cards?
Absolutely. Cashback sites track online orders only, so they work perfectly alongside in-store loyalty cards. For online orders, use cashback sites plus your loyalty card login for double savings.
How long does cashback take to arrive?
Typical timescale is 3-6 months from purchase to payment. Retailers need time to confirm purchases and process returns before releasing commission to cashback sites.
Are receipt scanning apps worth the effort?
If you regularly buy branded products, yes. Shopmium often offers 50-100% cashback on items you’d buy anyway. Five minutes of scanning can save £5-10 per shop.
What’s better: Clubcard or Nectar?
Depends on where you shop. Clubcard points are worth double Nectar points (1p vs 0.5p), but Nectar has more partner retailers. Choose based on your main supermarket.
Can supermarkets increase prices to offset loyalty discounts?
The Guardian investigation found that some loyalty prices simply match competitors rather than offering true discounts. The CMA confirmed 92% of loyalty prices beat the store’s own regular prices, but shopping around remains essential.
Do I have to buy products on offer?
No. Use loyalty cards for all purchases to collect points, even on non-discounted items. Those points add up to vouchers you can spend later.
What if I forget my card?
Most loyalty cards and schemes let you scan receipts retrospectively through their apps to claim points. Tesco and Sainsbury’s both offer this feature. Do it within a few days while receipts are still readable.
Your plan for supermarket savings
Getting started takes less time than you think:
This week:
