The discount retailer held onto the crown once more, having been declared the most affordable supermarket for every month of 2026 to date. Consumer experts at Which? examined 87 everyday products across various supermarkets, with Aldi's basket totalling £153.34 on average. It edged out competitor Lidl with and without a Lidl Plus card by £2.83 (£157.17) and £2.87 (£157.21), respectively. Supermarket loyalty schemes also made a considerable impact on the final bill. Which?'s analysis involved checking and comparing the prices of 97 widely-purchased branded and own-brand items, including products such as milk, cheese, and Hovis sliced bread, reports the Express. Aldi came in £61.53 cheaper than October's most expensive supermarket, Waitrose, which averaged £216.87. It was roughly 40% more affordable than Waitrose, based on Which?'s findings. Asda (£183.47) slipped further down the rankings in October, with Tesco and Sainsbury's recording average totals of £181.77 (Tesco Clubcard) and £182.90 (Sainsbury's Nectar) this month. Nevertheless, Asda, alongside Morrisons (£186.77), came in cheaper than Tesco (£187.31) and Sainsbury's (£191.56) when loyalty discounts weren't applied. Which? explained: "The discounts offered by loyalty cards may sound good but that's only if you can access them. "Our research has found out that millions of people can't access loyalty promotions because they aren't eligible to join the supermarket scheme due to their age, lack of address or difficulties with the digital access." Which? continued: "Grocery inflation also increased from 2.3% to 2.5% in the four weeks until 4 October, according to Worldpanel by Numerator. This rise comes after a period of grocery inflation easing to its lowest since October 2024 in August." Prices were calculated across the month, then added up to get each supermarket's average total price. You can find the total save below.
