PULEEEEEEEEZE........WalMart doesn't sell anything different than any other retailer, thus the same can be said for any other retailer.
WALMART does sell stuff that everybody else sells. But there are two important things that you ignore:
1. WAL*MART SELLS MORE STUFF THAN OTHER RETAILERS!
2. WAL*MART SELLS FOR LESS.
PLEASE! WAL*MART is not just another company that sells stuff.
