Director of the price comparison site Johnny Stern said “enormous” price rises have been witnessed on a number of items, such as dairy, meat products and rice in the studied period.
“This month shows an overall rise of 5.9% on prices from September 2007- within which our staples have risen at nearly four times the rate.
“This shows that our regular purchases are those which are being hardest hit by the rising price of commodities and fuel, so shoppers still need to keep a close eye on what they’re spending,” he commented.
He urged consumers to look around for “better priced like-for-like items”, with regular savings the key to beating the credit crunch.
TNS Worldpanel has also reported an overall turnover growth at all grocers of 7.3% in the past year.
