Secondly, it would be slitting their own throats since the kind of person who buys that stuff doesn't relish the thought of seeing it on the shelves of wal-mart...
What is interesting in the story is that there is a kind of sneering quality about $300 shirts from Saks.

There is also a vast difference in quality between a $300 shirt from Saks and a $20 shirt from Wal Mart.
