How I Spend Less on Groceries: Yellow Stickers, Food Rescue & Smarter Shopping

My practical UK grocery-saving routine: reduced food, food-rescue apps, own-brand swaps, loyalty prices, cashback and meal planning — without promising you'll halve your bill.

Last updated: October 2026. Offers, markdown times and food-rescue availability vary by store and location.

I have saved money on groceries by changing how I shop, but the old headline saying I “cut my grocery bill in half” made a personal result sound too repeatable. This version focuses on methods you can test yourself.

Check reduced sections — but learn your own store

Yellow-sticker timing is not nationally fixed at 7pm. Different stores reduce food at different times and the final markdown depends on stock. Ask staff politely or notice the pattern in the shop you use.

Food rescue apps

Too Good To Go and similar services can offer surplus food for less, but contents are often variable. It works best when you can genuinely use what you collect.

Own-brand swaps

I compare the item rather than the packaging. Where my family is happy with an own-brand version, I keep the cheaper swap. Where we genuinely prefer another product, I don’t force it.

Loyalty prices can help — but still compare

The Competition and Markets Authority examined around 50,000 loyalty-price promotions and found that most represented a genuine saving against the supermarket’s usual price. It also found examples where another supermarket was cheaper, so a loyalty badge does not replace comparison.

Cashback is the last layer

I have personally used cashback for years. I check it after deciding what I need, not before. See my cashback guide.

Five useful habits

  1. Plan meals around food you already have.
  2. Make a list before shopping.
  3. Compare unit prices where useful.
  4. Freeze suitable reduced food safely where appropriate.
  5. Track actual weekly spend so you know whether a saving method works.
