The total cost of a basket of groceries continued to fall last month, allowing shoppers to enjoy a sustained period of discounting on popular items.
A basket of 35 consumer goods cost £82.59 in May, compared with £86.60 year on year, the lowest price record since the mySupermarket Groceries Tracker began in December 2014.
From recent figures, it appears that the ongoing supermarket price wars have brought lasting cuts to grocery prices. Shoppers in Britain are now 8.5% better off on their weekly shop than in December 2014, saving £397.80 over the year.
Nonetheless, mySupermarket Managing Director Kim Ludlow warned that shoppers should remain vigilant.
"We're noticing a trend in total basket price dropping - yes, that's a fact. However, many products are fluctuating month to month and it's in shoppers' best interests to be across how their favourites are faring.
"Always check before you shop. Whilst you might select a retailer because its broccoli prices are lower than last year, if you look carefully you do notice that they are in fact more expensive than last month.
"It's becoming more and more difficult for shoppers to keep track of discounts and promotions so always compare your basket before you shop" Ludlow added.
