Question regarding retail return policy

[jedisinclair]

Anyone work retail or understand the "ins and outs", I have a question. I have a friend who bought a PS3 about 3 weeks ago. I talked him into it for the obvious Blu-ray abilities along with the fact that he wanted a new game system for his new hdtv. Anyway, he went on vacation and has NOT opened his PS3 yet. I told him to wait to open it because of the upcoming price drop and 5 free movie promotion. My question is this: if he takes his PS3 back to the store (I think he bought it at Game Stop)... with the receipt on July 12th and asks for a refund, would he get it? I mean, if the price drops on the 12th (he will turn around and buy one for $499, maybe from the same store) can they say "no" because it's cheaper? Or do they have to honor the fact that it's less than 30 days, he has the original receipt, and the box is still sealed and unopened? Just curious...
