The 'Wal' Rocks

The lines in a BW article read

The fallout is evident: After closing 70 stores in February, Circuit City Stores (CC) on Mar. 28 laid off 3,400 employees and put its 800 Canadian stores on the block. Tweeter Home Entertainment Group (TWTR), the high-end home entertainment store, is shuttering 49 of its 153 stores and dismissed 650 workers. Dallas-based CompUSA is closing 126 of its 229 stores, and regional retailer Rex Stores (RSC) is boarding up dozens of outlets, as well as selling 94 of its 211 stores.

And all these are attributed to "WalMart Effect". We all know, they strive for the lowest prices but... WalMart is making disastrous differences. They are not only stopping the producers & manufacturers from deciding the prices and reaching out the customers, but now even the other retailers are not finding ways to stop WalMart.
Well, the above fall is attributed to the slashing of prices by WalMart in the Plasma & LCD TV segments.
Can 'Warehouse' based stores make some difference in this so that the 'Wal' can be made weak?
