Taking place at Sainsbury’s Pimlico store in London, the retailer will be the first supermarket to offer collection times of under an hour. Customers will be able to select and pay for up to 25 items for collection in 30 minutes, seven days a week with no charges for the service. Clodagh Moriarty, director of online at Sainsbury’s, said: “The way customers are shopping is changing as they look for faster and more convenient options and we want to continue leading the way in giving them the services they need to shop wherever and whenever they want.”
