TESCO in Wadebridge is about to start a "drive-through'' service for customers.
Shoppers will be able to pick up their groceries without leaving their cars.
Customers drive up to a signposted collection point and pull into a covered area to show staff their shopping reference details.
Staff come to the customer's car window, so there is no need to get out, and the shopping is then packed into the boot.
Customers order their shopping on the tesco.com website choosing the 'Click & Collect' option and booking a two-hour collection slot. They can then collect anytime within this two-hour window with collection slots available seven days a week.
As with home delivery orders, the service charge (from £2) is added to the shopping bill.
"We believe this will be especially popular with busy mums who have the school run and children's activities to manage," said Simon Belsham, managing director of Tesco Grocery Home Shopping.
"It offers a convenient solution to parents who want to avoid the challenge of shopping in a busy store with children in tow but can't afford the time to stay in for the shopping to arrive at their door."
Local schoolchildren will be invited to design artwork for a special jute shopping bag to help launch the new Click & Collect service.
