Aldi retained its title as Britain’s cheapest supermarket for the sixth month in a row. Latest analysis from the consumer champion Which? It showed shoppers could save up to £66.54 at the discount supermarket chain compared to June’s priciest store.
Aldi maintained the momentum from its 2025 overall win, claiming the title in 10 of the 12 months. It was only beaten by Lidl in July and October last year. The loyalty price war is also heating up, with Sainsbury’s Nectar overtaking Tesco’s Clubcard as the cheaper option on Which’s shopping list?

Based on the store’s stock of 95 popular branded and own-brand products, including milk, cheese and Hovis sliced bread, Aldi shoppers paid an average of £163.34.
With Lidl Plus discounts, Lidl came in second with an average price of £164.79. Without Lidl Plus discounts the store’s price was £164.92; the difference was only 13p.
Asda came fourth, costing shoppers £190.39 for the 95-item list. Sainsbury’s with Nectar followed at £193.30, followed by Tesco with Clubcard at £194.67 and Morrisons and More at £198.41.
Waitrose was again the most expensive supermarket in the monthly analysis, with the same products selling for an average price of £229.88 throughout June. This represented an average difference of £66.54, or almost 41%, compared to Aldi.
Supermarket loyalty cards can make a visible difference

The analysis also revealed the difference having supermarket loyalty can make. According to Which, a loyalty card will save you an average of 2.97% at Tesco and 5.17% at Sainsbury’s over the month, while you’ll save a much smaller 0.08% at Lidl.
Lidl changed its loyalty card scheme in May, allowing customers to collect points instead of receiving reward vouchers. Every pound spent now equals one point, making the scheme compatible with both Nectar and Clubcard.
Last month, Tesco announced a new Clubcard for 16 and 17-year-olds after campaigners called on supermarkets to remove unfair restrictions on loyalty schemes so more people can benefit from lower prices.
What is the UK’s food price inflation rate?
Grocery price inflation fell to 3% in the four weeks to June 14, according to Worldpanel by Numerator. Shoppers turned to promotions to keep costs down; Last month, 30.4% of sales, including the agreement, were 28.4% compared to the previous year.
As the FIFA Men’s World Cup continues, football fan favorites saw their highest promotional activity in five years in June. Deals can be found on beer, cider, snacks, chips and cold pizzas as retailers compete for customers stocking up ahead of matches.
Worldpanel head of retail and consumer insights Fraser McKevitt said: “Almost a third of grocery spend now goes towards promotion and this upward trend shows no signs of breaking.
“Coupled with strong online growth, this points to shoppers who know what they want and are increasingly confident about where and how to find the best deal. In short, retailers are having to compete hard for the summer store.”
