Britons using Tesco Clubcard and Sainsbury’s Nectar more as costs at the checkout continue to rise

Grocery price inflation has eased to 14.9%, the lowest rate since Christmas, as supermarket shoppers sought out loyalty card promotions.

The fall in inflation over the four weeks to 9 July was partly the result of shoppers spending more via schemes such as Tesco’s Clubcard and Sainsbury’s Nectar, but it was also driven by a comparison with a step up in inflation a year ago.
