Sainsbury's shoppers who hold a Nectar card has been issued a warning - as a study showed they could be paying £615 more a year compared with a budget supermarket. A study from consumer group Which? found that shoppers who subscribe to the Nectar loyalty card scheme, which offers cheaper prices on some items, are still paying more for some items than if they shopped at Aldi, which was found to be the cheapest UK supermarket of 2024 in the same study.

The study compared the cost of groceries at the UK's biggest supermarkets every day throughout 2024 to determine how each chain compared in price. In order to assess how supermarkets compared in terms of price, the consumer watchdog analysed the cost of up to 200 branded and own-brand products every day over the course of a month - from Heinz beans to own-label milk.
The average costs were tallied up to reach a grand total for each retailer - which included special offers and loyalty prices where applicable. The group found Aldi was the cheapest supermarket across all twelve months, making it the most affordable supermarket of 2024.
Lidl came in at a close second, charging just £1.99 more than Aldi on average each month. Meanwhile, analysis found Waitrose to be the most expensive supermarket for shopping across all months in 2024.
