RougeFemme writes "Amazon has been placing lockers in brick-and-mortar retail stores, such as 7-Eleven, for pickup of online purchases. Walmart plans to pilot a similar program, presumably making it easier to pick up online purchases at Wal-Mart. 'Wal-Mart hopes its network of physical stores, which number about 4,000 in the United States, will give it an edge as consumers increasingly use smart phones while they shop. Wal-Mart has been testing the shipping of online orders from a small number of its physical stores for about two years. In 2013, the company plans to expand this program from about 25 stores currently to a total of roughly 50 stores. ... Two-thirds of the U.S. population live within five miles of a Wal-Mart store."
