About Sainsbury’s

Sainsbury’s is one of the UK’s largest supermarkets, serving millions of shoppers every week through large superstores, Sainsbury’s Local convenience shops and its online grocery service. Founded in 1869, it has become a fixture of the British high street and a regular stop for the weekly food shop. Shoppers can browse fresh fruit and vegetables, meat and fish, bakery items, chilled and frozen ranges, store cupboard staples, household products and toiletries, alongside own-label tiers that run from everyday budget lines up to the premium Taste the Difference range. Many larger stores also stock Tu clothing, homeware and small electricals, so a single trip can cover far more than groceries. Online grocery delivery and click and collect make it easy to order a full shop from home, while Nectar members can collect points and unlock Nectar Prices on selected products. With tuck., you can add another layer of value on top: buy a Sainsbury’s gift card in the app before you pay, receive your cashback in your tuck. wallet straight away, then use the gift card for eligible purchases in line with the current gift card terms shown in the app.

Sainsbury's cashback cards purchased through tuck. work exactly like regular payment cards - use them in-store and online without any restrictions. The only difference: tuck. gives you money back the moment you buy.

With tuck., you get up to 4.25% cashback every time you shop at Sainsbury's. That's real money back - not points, not vouchers, not a rebate in 90 days.
