Wal-Mart Weirdness?

Well I went to Wal-Mart yesterday to buy some stuff. I checked the toys department and, of course, they had nothing. The strange thing is, not too long ago, the shelf was completely full of the BB-Barricade 2-pack. Im pretty sure those things didnt sell out THAT quickly, considering how many they had when i checked before. Also, they had replaced the previous 2-pack shelf with, I believe it was Star Wars toys.
So, I checked the other toy aisles, and noticed there were quite a few maroon-shirt workers just scanning random items. After unable to find any other Transformers toys, I moved on. Then I noticed these same maroon-shirts all aroudn the store, scanning the electronics items, clothing items, and even food items. What are they doing? Who are they? Do they have anything to do with TF's?
