Waitrose is considering using GPS technology on customers’ mobile phones to help it prepare click-and-collect orders when shoppers are nearing stores.

Sources told the Telegraph that the service would likely be run through a smartphone app, which would recognise when click-and-collect customers were close to the store.

Waitrose said there were no plans in place to test the technology as of yet but it was one of the many ideas being studied as the grocer strives to improve customer service.

At present shoppers can pick up online orders at 160 Waitrose stores and the retailer launched a drive-thru service in Cheltenham in February. It is also trialling collection lockers for online orders.
