Sainsbury’s has scrapped a trial of wi-fi in store which it introduced earlier this year.

The grocer trialled the service for customers at three of its superstores in Crayford, Stanway and Lincoln in February.

A Sainsbury’s spokeswoman said: “We currently do not have wi-fi enabled in our stores. We trialled free wi-fi for customers but decided not to pursue it.”

The grocer declined to elaborate on why it had decided not to offer the service or whether it would ever be re-introduced.

The move comes as Marks & Spencer revealed yesterday that it is to offer free wi-fi in all of its UK stores from next May.

Tesco completed the roll out of wi-fi to all of its 250 large Extra stores last November. The service is also available in 27 Metro stores, nine HomePlus stores and 174 superstores. The remaining superstores will receive the service within the next month.

Asda is trialling wi-fi in store at a number of larger stores while Morrisons has rolled out the service to cafés in nine of its Fresh Format stores.

Wi-fi allows shoppers to easily browse extended ranges and compare the price of products at different retailers on their mobile device. It is also used by retailers to drive footfall by those who need to use the internet on the move.
