The good news? You can turn your regular shop into a reward opportunity by using cashback deals, loyalty programs, and smart wallet strategies.

This guide covers how to save money on groceries using cashback, which apps and cards to use, and how to stack rewards with tools like Curve Pay to get more from your food shop—without changing where or how you shop.

How to Save Money on Weekly Grocery Shopping

Cutting back doesn’t have to mean buying less—it just means shopping smarter. Simple changes like planning meals, buying own-brand products, and using loyalty programs can save you up to 30% on your weekly bill.

But if you're not already earning cashback on top, you're leaving money on the table.

If you want to know how to cut costs with everyday shopping you should start with  combining store loyalty schemes, cashback platforms, and Curve Pay’s own 1% cashback on foreign currency spend and retailer-specific offers, you can earn rewards from multiple sources—even on budget buys.

How to Use Cashback to Save on Groceries

Cashback works by returning a small % of your purchase after you spend. You can earn it through:

• Loyalty programs (e.g. Tesco Clubcard, Sainsbury’s Nectar, M&S Sparks)
• Cashback sites and apps like JamDoughnut, Airtime Rewards, and TopCashback
• Curve Pay, which lets you earn cashback on top of your existing card and store rewards
  
  

Here’s how to stack it:

1. Scan your store loyalty card at checkout
2. Pay with a cashback card linked to Curve Pay
3. Activate any cashback app deals before shopping
4. Use Go Back in Time® via Curve if you forgot to use your cashback-linked card
   
   

By using Curve Pay as the payment layer, you also gain real-time spend alerts and Smart Rules to assign the best card for the category. This lets you combine cashback with Curve Pay and automate grocery savings without needing to switch banks or cards.

Compare Supermarket Deals for Extra Cashback

Some supermarkets offer more cashback potential than others. Use price comparison tools like Trolley.co.uk  or LatestDeals to spot the best prices before you shop. Then layer in cashback for bonus savings.

Here’s a quick look at where you can stack rewards:

How to Use Shopping Lists & Meal Planning to Avoid Overspending

Cashback is powerful, but pairing it with a good strategy matters. Planning meals and writing a focused shopping list can prevent food waste and impulse buys.

Sites like goodFood recommend starting with your existing cupboard items and building a weekly plan from there—then sticking to your list in-store.

Combined with cashback, this helps you stay on budget and build up rewards with every planned purchase.

Can You Combine Cashback with Promo Codes or Coupons?

Yes—but be careful. Most cashback sites only allow approved voucher codes. Using unlisted promo codes or third-party influencer coupons can cancel out your cashback.

Curve Pay helps here by keeping track of which card was used, how cashback was applied, and allowing you to change cards after the fact if needed.

Stacking Curve Pay with Supermarket Cashback: A Practical Example

Here’s how a typical cashback stack looks at Sainsbury’s:

• Scan your Nectar card for base points
• Activate a JamDoughnut app offer
• Pay using Curve Pay linked to a cashback credit card
• Earn Curve Pay cashback on the transaction if it’s a featured retailer
  
  

This lets you earn rewards from the store, your card, the app, and Curve—all from a single transaction.
