Shoppers who use a Tesco Clubcard to get their groceries each week are being told they are spending £14.78 per week more than customers who shop at Aldi for the same basket of goods.
If the same price gap were to be maintained over a year of weekly food shops, that would mean Tesco customers would be parting with £768.56 more for their shopping than Aldi shoppers, even if they have a Clubcard and take advantage of the loyalty discounts. New figures released by consumer magazine Which? show that Aldi was once again named cheapest UK supermarket for May, with a basket of 82 staple goods coming in at £135.48 in its analysis.
Second was Lidl, just 31p more at £135.79 including Lidl Plus prices, while Asda was third, at £149.94.
It put Tesco in fourth place for those who have a Clubcard, with a £150.26 price, or £152.35 for those without a Clubcard, while Sainsbury’s was in fifth place for those with Nectar cards, at £151.82.
It means that someone buying the same basket of 82 goods in Tesco with a Clubcard every week for a year would end up spending £768.56 more than an Aldi customer buying the same equivalent goods, if they shopped each week and the same price gap were maintained.
In a separate test for a larger basket of goods including items not available in Aldi and Lidl, Asda came out on top at £485.79, followed by Tesco Clubcard shoppers in second at £496.59 and Sainsbury’s in third at £498.72, according to Which?’s figures.
Waitrose was the most expensive on average, with the bigger shop costing £559.02 – a difference of £73.23 compared to Asda – 15 per cent more.
Waitrose was also the most expensive supermarket for a smaller list of items this month, totalling £184.03 on average – a difference of £48.55 compared to Aldi – 36 per cent more.
The list of 82 items included both branded and own-brand items, such as Birds Eye Peas, Hovis bread, milk and butter.
Reena Sewraz, Which? Retail Editor, said: “Aldi continues to be the UK’s cheapest supermarket in our monthly price analysis for May while Lidl has narrowed the gap to just 31p. For a bigger list of groceries, Asda continues to be the cheapest supermarket, beating shopping at Tesco with a Clubcard by more than £10.
“Food prices are still high and are likely to rise again so many people will be looking to cut costs where they can. Our analysis shows that by switching supermarkets, shoppers could pay up to 36% less, highlighting the advantages of shopping around where possible.”
