A friend of mine told me a story about how he and another friend of his called a gamestop they were standing outside of. While looking at the employee who answered the phone, he asked if they had Guitar Hero III available. Then the employee replied that they were sold out.
However, after that cellphone call, they both entered and asked the SAME guy if they had Guitar Hero III.
They did have it.
The same shit happens to me every time I go there for a game that just came out.
