Sainsbury’s more expensive than Waitrose for shoppers without loyalty cards

Sainsbury’s has been named the UK’s most expensive supermarket for shoppers without a loyalty card, according to research by Which?

In its monthly comparison of the price of an average food shop at six of the UK’s biggest supermarkets, the consumer champion found Sainsbury’s was - for the first time - more expensive than Waitrose.

The average trolly of 131 items came in at £395.23 in Sainsbury’s - £33.52 more expensive than Asda, who was the cheapest option, and £3.27 more than Waitrose.

The Which? analysis includes special offers available to all shoppers (other than multibuys), but not loyalty discounts, keeping the research as fair as possible. When the loyalty card offers were applied Sainsbury’s became cheaper than Waitrose.

The latest findings show that shoppers can make considerable savings on their food shop by shopping around and taking advantage of store loyalty cards.

Which? found Aldi the cheapest supermarket for a smaller basket of goods for the 16th consecutive time in a row, with a small food shop totalling £67.72 – £1.24 less than Lidl who was the second cheapest.

Aldi and Lidl are included in Which?’s smaller basket shop but not in its large trolly shop as they don’t always stock big-brand products.
