Wal-Mart doesn't want anyone sharing their pricing with competitors.
Do you think that two random employees from some Wal-Mart can't just walk into another competing store and memorize a few prices? Perhaps pick up a newspaper ad and scope out the price it's advertising to the public?
Wal-Mart has some odd policies. I've delivered to their stores many many times, and here are some of the things you must abide by or else you won't be allowed to deliver more product, or you could be refused at that moment;
1) Only one delivery person "in the red zone" at all times. This includes people from the same company. Two Budweiser employees cannot be getting the same load checked in.
2) You must have your product shown to the receiver, UPC's all scanned. So if you have 2 cases of frozen pizza, you have to show all three (even if all three are the same price)- not just one and they "do some math."
3) No swearing in the back room. I was almost thrown out of a store for this, because I showed my disdain for Wal-Mart, and the girl said "If you want to act that way, you can leave." I told my employee that I was going to get something to eat, and he said "Can't do it, it's Wal-Mart!" and I replied 'Jesus Christ!' But I was breaking rule number 1, so I didn't want to push my luck.
4) All products must meet a certain temperature, frozen food can't be any more than -10 degrees. If not, they'll refuse your product. They actually stick a thermometer in the product and have to log the temp in to a book, which will later be reviewed by a big wig.
5) Invoices must match up 100%, this rarely happens, and it becames a fiasco!
6) The receivers are worthless there. They'll hire 2 incompetent bible-thumping girls (like girl in #3), that can't check you in, in less than an hour and a half because they are paid $10/hr. Compare this to another store, the receiver will get twice that, and have you in and out within minutes because he knows what he's doing, and isn't stupid!
And lastly, a MANAGER from a Wal-Mart told me that he made $8/hr. I was shocked. This was in Nevada, so I'm sure that had something to do with it, but I couldn't believe it. Also, I think he was only a department manager, not a store manager.
Fuck Wal-Mart!!! But they do have good prices!
