Almost every international company that delivers mail order through its website will deliver to a London address. Here are some favorite sites of Londoners:
Amazon: http://www.amazon.co.uk
This website doesn’t really need a description, as it’s such a household name. Get new and used books and DVDs and everything from clothing to pet gear here. Delivery is fast.
Argos: http://www.argos.co.uk
Anyone who’s lived in London knows Argos. This catalog/online only shop carries a massive selection of items from electronics, including computers, to bedding to furniture to jewelry and sporting goods. Argos is known for its low prices. Because there are no displays to view the products, prices are kept down. Obviously, it’s not always easy to purchase something you can’t physically see and touch, but Argos is a bargain and an institution. You can order online but there is a fee for delivery. Many Londoners reserve their goods online to pick up in shop. Shops are in major neighborhoods. Try to get there weekdays, as queues can be heavy on weekends. The system of waiting, paying, getting a number, and picking up your stuff is an activity most Londoners will experience at some point at Argos.
