However when comparing the cost of a larger trolley of 149 items, excluding Aldi and Lidl, Asda was found to be the least expensive for £355.62.
Sainsbury’s took second spot at £368.97, while Tesco was £7 more expensive at £375.97.
Waitrose was again the most expensive of the supermarket giants, the only one to cross the £400 barrier at £6.95 over.
Across all 12 months last year, Aldi was found to be the cheapest for seven, more than any other grocery retailer.
However, Lidl was found to be the cheapest for the first five months of 2022, with the average price difference between the two in the past seven months being £1.59.
This comes as new research by Moody’s found that Morrisons raised its prices more than any other major UK supermaket last year, causing shoppers to switch to rivals.
The credit rating agency said it “rapidly” hiked prices in June and was the only supermarket giant to raise prices faster than Lidl and Aldi.
