In the United Kingdom and in Denver, CO, Walmart has been experimenting with “click and collect.” This is a process by which consumers purchase goods online and then go to a physical store to pick up the order. It is possible to purchase even perishable items for pickup, because orders are stored in refrigerated lockers of varying temperatures. This practice is old hat to Europe, which has been using click and collect for some years now, but it stands poised to become a major source of growth in the United States.
The benefit of click and collect over direct delivery is that you need to be at home to receive a direct order, and lockers are much safer than leaving a delivery on an unguarded doorstep. It also makes truck deliveries less complicated, as more goods can be shipped straight to store. You can expect to start seeing this phenomenon crop up at other Walmarts soon, and then at other businesses entirely.
