Wal-Mart has millions of customers visiting its stores each week. Some of these shoppers could tell the retailer where they live and sign up to drop off packages for online customers who live on their route back home, Anderson explained. Wal-Mart would offer a discount on the customers shopping bill, effectively covering the cost of their gas in return for the delivery of packages, he added. “This is at the brain-storming stage, but its possible in a year or two,” said Jeff McAllister, senior vice president of Walmart U.S. innovations.
