LOL $hady
Honestly though, if you buy it from Wally World, be assured they WILL note the serial # and track it vigorously.
Also, EB/GS do that as well, at least they did with a used Playstation I bought from them.
I got a funny look from a manager when I brought back another Playstation that I had bought elsewhere for like $1 and tried to return it as the one I had bought from them.
He still did the return though, but you may end up blackballed from either Wal*Mart(wally world) or EB/GS, if they are as thorough in their serial number documentation as I noted.
Heck, I used to take full advantage of the fact my local EB stores never had a universal price across the board on games at all stores. I would buy a game from one store, then return it to another store 10-20 miles away for their full price.
I did this way back in the 16 bit era, but it still held true for part of the PS1/N64 era.
Nowadays though, you'll be lucky if EB/GS give you trade in value of even an UNopened game/game system if you try to return it after their return policy states.
