Lidl has surpassed Aldi to become the UK's cheapest supermarket for the first time in nearly two years, according to a July price analysis by consumer group Which?.
The analysis of 76 grocery products revealed Lidl's average basket cost £128 with a loyalty card, marginally less than Aldi's £129.25.
Both discount retailers were significantly more affordable than other supermarkets, with Tesco costing approximately £17 more and Waitrose, the most expensive, costing £40 more at £170.91.
Which? noted that loyalty cards offer substantial savings, particularly at supermarkets such as Tesco and Sainsbury's, while Morrisons did not outperform competitors on price.
The ongoing price competition among supermarkets is driven by high food inflation and the cost of living crisis, leading many consumers to alter their shopping habits in search of better value.
