Supermarket price comparison

By Hannah Walsh

Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

Discover which is the cheapest supermarket this month, based on our exclusive price comparison analysis.


Every month, we compare how much the big supermarkets charge for a basket of groceries, including everything from bread to toothpaste. 

Our comparison is based on the prices advertised by online supermarkets Asda, Sainsbury’s, Morrisons, Tesco, Waitrose Deliver and Ocado for between 60 and 100 popular branded food and grocery items. We focus on big brands that people commonly buy, such as Andrex, Lurpak, Warburtons and Heinz.

Every month, you can see how the supermarkets compare - and discover which is cheapest.
