I thought I might clarify-

For anyone who *doesn't* know what Wal-Mart is, it is a multinational conglomerate chain of superstores ofering everything from food and produce to clothing and hardware. Essentially, the move into neighborhoods offering slightly lower prices for items than their competitors, and conveniently offer them all in one building, and push out smaller businesses. Once they have attained the appropriate customer base (as many people as possible) and have everyone used to going to Wal Mart, they raise their prices higher than their competitors were, and now prey on the consumer who now isn;t used to shopping in several places for several things.

In other words, they are a virus and they are spreading.
