Customers who order via the Click and Collect service at check-out will have 10 days to pick up their parcel from their chosen local shop, where their item will be delivered.
Those who order through Click and Collect before 26 March will be automatically entered into a competition to win a £500 cash prize.
The service includes a next-day delivery option. Customers can also take unwanted items back to their local Collect+ shop to receive a refund.
Courier service Collect+ runs a free next-day Click and Collect service for Littlewoods-owned online retailer Very.
Customers can pick up their orders in participating retailers, which include Co-op, Spar, McColls, Costcutter, Sainsbury's Local, One Stop and Londis.
Click and Collect is increasingly growing traction with customers and its popularity boomed last Christmas.
