Tesco, Sainsbury's, Morrisons, Asda shoppers warned they could lose £713 each

Asda, Tesco, Sainsbury's and Morrisons shoppers risk losing over £700 each by the end of 2025. Those who opt to shop with the traditional Big Four retailers - Asda, Morrisons, Tesco and Sainsbury's - rather than budget favourites like Aldi and Lidl risk being left hundreds out of pocket.

Shoppers at four top supermarkets face higher weekly shopping costs than at German supermarket Aldi, which Which? has found to be the cheapest in the country, as well as Lidl.

On average, Tesco shoppers pay £10.98 per basket on average, Which? says, while Asda pay £12.93, Morrisons fork out £13.72 more and Sainsbury's shoppers pay £11.84 more per basket. It means, over a year, Morrisons shoppers would pay £713.44 more than Aldi customers.

It comes as Aldi is giving away a whopping £20,000 worth of vouchers, equivalent to four years’ worth of grocery shopping, as new research reveals it to be the cheapest supermarket for the fourth consecutive year.

In its annual price comparison research, Which? found Aldi to be on average £131.13 cheaper per month than Waitrose throughout 2024.
