Nearly one in five of Tesco’s and Sainsbury’s local store customers say the multiples’ moves into the convenience market have transformed the way they shop, according to exclusive research for The Grocer.

A survey of 1,721 principal shoppers, conducted by market research company HI Europe, has found that 17% of those using Tesco Metro/Express and Sainsbury’s Local believe their shopping habits have changed since these fascias opened.

Over half say these stores are a welcome addition to the high street, bringing more choice and variety than traditional convenience stores, while 38% say they are pushing up the quality of products available on the high street.

However, 21% say these fascias do not offer better value for money on the high street and 40% recognise that prices are more expensive than in the supermarkets of the same name.
