I have seen that video, it is about what 9 or 10 years old? there is also a new one showing the changes, have you seen that one? The thing about them going into towns and lowering prices and putting them out of buisness and raising prices back, was NEVER actually proven. A third party, unaffiliated with wal mart, did a survey of such said wal mart and over about 10-15 years the prices only went up about 2.5-5%
