Shopping at smaller convenience stores instead of full-sized supermarkets could be costing you an extra £300 each year, consumer champion Which? has warned.
In a new check list released today, Which? said households spend up to £10.20 more each week at a Sainsbury’s Local rather than a regular Sainsbury’s supermarket.
This was the biggest difference spotted by the consumer magazine over the course of a year. Over the 12-month period, the average weekly difference added up to a staggering £322 over the course of a year.
