take a course in marketing, dummy. It's called a loss leader. WMT buys from AAPL and sells them at a loss to get people to come in their stores. Keep in mind, they are only available in supercenter stores and not online. It is the same as AMZN selling their tablet for a loss. It's ok, borderline genius when AMZN does something like that, but when WMT does it, it must be a black eye for AAPL.
