I know this is a little off topic, but that post mentioning Wal-mart reminded me of my buddy. It has to be the funniest wal-mart story.
A buddy of mine had a barcode making program. So he went to wal-mart and did some homework to find 2 similar things that were very differently priced. He decided on a b-b-gun. One of them was 120 dollars, and another was 11. He went home, printed up the barcode for the $11 one, went back, and put it on the $120 gun. Bought it for 11 something and went to another Wal-mart and returned it for 120 something. It was halarious.
