LOYALTY PRICES UNABLE TO BEAT ALDI PRICES FOR A WHOLE YEAR – PROVEN BY WHICH? INDEPENDENT RESEARCH 

3 July, 2025

• New research from Which? has revealed that Aldi is still the cheapest place to buy everyday supermarket essentials, even after factoring in loyalty prices 
• Shoppers can save £850¹ each year by switching from Sainsbury’s to Aldi – even with a Nectar Card 

Research by consumer group Which? has found that Aldi is yet again the cheapest supermarket for 79 essential items this month.

The total price of a shop at the discount retailer came in at £47.12 less than Waitrose, as well as being cheaper than Ocado by £33.99, andless expensive than Sainsbury’s by £22.26.

That makes it an entire year that Aldi has come out on top against loyalty card prices, beating Sainsbury’s Nectar Card prices by £16.77 and Tesco Clubcard prices by £15.17. Loyalty card shoppers could have saved more than £850² in the last year by switching to Aldi – that’s enough for a holiday to Santorini!³

Julie Ashfield, Chief Commercial Officer at Aldi UK, said: “Introducing loyalty prices to the Which? research has only reaffirmed our stance that we will not be beaten on price. We are proud to make it an entire year of wins since the loyalty prices were introduced, and vow to keep providing shoppers with the best possible value.”
