Chop Chop exists as a standalone iOS app that was developed by the company's in-house Digital Lab. Right now, it's only available in Wandsworth, serving within three kilometers from its local store, and offers customers 20 specially-picked products. This trial, Sainsbury's says, "is part of our strategy to give our customers more options to shop with us whenever and wherever they want."

Although it's very limited at the moment, Sainsbury's CEO Mike Coupe has confirmed that the supermarket sees demand for having a basket of food delivered in a short amount of time. This, of course, would exist alongside the company's existing home delivery service and its network of local shops and megastores, allowing customers to grab groceries without having to deviate from their schedule.
