It's all just blah blah blah.
If a company doesn't like Wal-marts demands they don't have to give in to them. example the clean dvd's.
And saying that Wal-Mart put the other companies out of business is speculation. Except maybe K-mart.
And the what-if in 10-20 years. Good lord it's probably like the game industry , the whole Atrai then Nintendo , now Sony thing. Some other company will probably come and put Wal-Mart out of business just like Wal-Mart did to K-Mart. Who would have thought that would have happened ?
