Sainsbury's shoppers have been issued a £624 warning over holding a Nectar card. Those who are subscribed to the supermarket giant's loyalty card scheme have been warned over the difference in price between the retailer and budget favourite Aldi.

Which? checked the cost of a trolley of groceries at the UK's biggest supermarkets every day throughout 2024, and revealed the results each month. Aldi was the cheapest supermarket for all 12 months of the year, making it the cheapest supermarket of 2024 according to our analysis.

Lidl was the second-cheapest supermarket every month, charging £1.99 more than Aldi on average. Waitrose was the most expensive supermarket for our shopping list in every month of 2024. The consumer watchdog said: "Waitrose was the most expensive for our bigger shop every month except September, when Sainsbury's was priciest (for shoppers not using a Nectar card).

"Our price comparison includes discounts that are available to everyone and loyalty prices where applicable, but not multibuys." Aldi was the cheapest supermarket in December, charging £100.29 on average for our shopping list of 56 branded and own-label groceries.

Sainsbury's customers who have a Nectar card paid £112.13 and those without paid £116 - with Nectar card holders having a £12 difference per weekly shop, or £624. Harry Rose, editor of Which? magazine, said: “Our research shows Aldi has retained its crown as the UK’s cheapest supermarket in 2024.

“After the added expense of the festive period, many households will be looking to cut costs. Our analysis shows that by switching supermarkets, shoppers can make significant savings, highlighting the advantages of shopping around where possible.”

Tesco was the cheapest of the traditional supermarkets – the shopping cost £111.22 if you have a Clubcard, and £112.90 if not. Waitrose was the most expensive supermarket at £129.83 – nearly £30 more than Aldi.
