You woud be surprised by how bad K-Mart, which merged with Sears, is at keeping things you need in stock. If you want to buy something commonplace, like a particular model of Crock Pot or a particular Corelle dish, odds are about10% that the nearest K-Mart has it vs about 90% that Wal Mart has it. Clearly there is still a big difference enabled by Wal Mart&#x27;s IT and business processes. Especially since once the odds of wasting time and a car trip go up just a bit the backstop is to order the thing from Amazon.
