I work for Wal-Mart(not in the store), and when I bought my PS3 I didn't have my employee discount card on me(10%), so they told me when I got it just bring it back and they would give me the 10% back. Well when I went to return it they wouldn't let me buy the old one back, I had to actually go get another of the shelves. They didn't even look in the box at all, I could have put anything in there and they would have never known. I asked if they put them back on the shelves when they are returned non-defective, ad she said all open merchandise goes back to the company.
