I recenty bought a psn card, and when I scratched off the tab to reveal the code, it started to oddly smear out the code, making it illegible. So I tried to return it to the gamestop I bought it at, but they said they're not allowed be return cards like this. Then they give me the advice of trying to see if I can get the points by showing the barcode/ID number on the card to someone at sony.
I'm not sure if sony actually checks the forums, but just to be sure, I ask, could someone check the barcode/ID to get the redeem code? or something along those lines?
