Asda cheapest on a big shop
Which? also compared the cost of a larger trolley of 149 items – the original 48, plus 101 more. This shop included a larger number of branded items, such as Andrex toilet paper and Cathedral City cheese, and did not include discounter supermarkets Aldi and Lidl, which do not always stock some of these products.
Asda cost the least for this larger trolley of groceries, as the cheapest traditional supermarket. It cost £355.34, on average, for this shop, beating the next cheapest, Sainsbury’s (£366.83), by £11.49.
Waitrose was £38.03 more expensive than Asda, coming in at £393.37, on average, for the trolley of comparable goods.
Which? recently launched its Affordable Food For All campaign. The consumer champion is calling on supermarkets to provide the support people around the country desperately need in order to keep food on the table during the ongoing cost of living crisis.
‘Some supermarkets considerably more expensive than others’
Reena Sewraz, Which? Retail Editor, said: “No one wants to overpay for basic groceries, especially in the build-up to the festive season when many household budgets will be stretched.
“Our findings show that while prices are going up, some supermarkets are significantly more expensive than others. As well as choosing a supermarket that is cheap overall, other ways to save include swapping from branded to supermarket own-brand products, sticking to a shopping list, and resisting the temptation to pick up special offers you don’t need.”
