Sainsbury's Discount Codes - May 2025

Big Savings with Nectar Card

With a Nectar card, you'll earn points every time you shop. Whether that’s a big weekly grocery order or just nipping to your local Sainsbury's to pick up a few essentials - those points will soon start building up.

Once you've got enough points, cash them in for exciting rewards and exclusive discounts. As a member you’ll also receive offers, discounts and bonus points based on the things you buy - savings that really count. Download the Nectar app to get started.

Saving tip from your Sainsbury's deals expert, Yasmeen Lubbock:

If you don't mind sharing, my recommendation is to open joint points accounts at your local supermarket branch. My housemate and I share a Nectar account: she uses the app and I use the physical card when we do food shops for the house. Sharing an account for the household means we collect double the number of points and vouchers than if we had two separate accounts!

Most recently we received £15 worth of Sainsbury's vouchers that meant we got almost our entire weekly food shop for free! And of course, having the Nectar Card means our food shop is often slightly less as we never miss a Sainsbury's offer like Nectar price crisps, dips, ice cream and more.

Lowest prices with substitution promise

We all hate that dreaded substitutions list when we order our groceries online. Pigs in blankets swapped for original cocktail sausages? No, thanks! Thanks to the Sainsbury’s substitution promise you’ll get a voucher for the difference if your substitution is more expensive than the item you ordered. If you’re not happy, hand anything you don’t want back to your driver - no questions asked - for a refund within five working days.

Look out for the Sainsbury's sale

Check out the sale tab for big discounts on a wide selection of homeware, kitchenware, electricals and much more. From outdoor grilling and barbeque favourites in Summer, or delightful Christmas treats (like mince pies and roast chicken) in January - you're sure to find an amazing deal to get more from your weekly food shop.
