The cost of a weekly shop has dropped by more than 5% in the last year, according to

The independent shopping and comparison website’s just-launched mySupermarket Groceries Tracker service found that a shopping basket in January 2015 cost £88.13 – a fall of 5.09% compared to January 2014, when the same basket cost £92.86 and a drop of 2.33% compared to December 2014 when it would have been £90.24.

The tracker, an industry first, compares the basket price of the same 35 products each month that are most commonly bought at supermarkets. It covers almost 5,000 products overall and includes Tesco, Asda, Aldi, Sainsbury’s, Ocado, Waitrose and Morrisons.

Products that have undergone a price drop in the last month include eggs (-7.7%), broccoli (-15%) and grapes (-14.5%), while products on the ascent included branded and own-brand cola drinks (+3.25%), squash drinks (+2.18%) and carrots (+1%).

Gilad Simhony, chief executive of mySupermarket, said: “With a saving of almost a fiver on their weekly shop compared to a year ago, shoppers up and down the UK should be delighted to see a welcome break in one area of their personal finances.

Big savings

“This is great news for shoppers and demonstrates the impact of the supermarket price war. We still see, however, that items change in price frequently across all of the supermarkets, meaning it is more important than ever to compare prices as the difference between supermarkets as well as brand and own-brand items can be huge.”

The mySupermarket Groceries Tracker will also look at own-brand categories and each month reveal the best supermarket for each type of own-brand groceries.
