Hello All, I got 2 PSP for two of my nephews. the problem now is i bought one from Best Buy one from Future Shop. But I mixed them up, after wrapping them. Now i need to give the recipt to thier parents. Does it matter which reciept to them. I unwrap them, the Barcode on the two boxes seems to be the same, the only differnt thing seems to be the serial. my question is, does it matter which reciept to give them in case they want to refund it?? reworded: is the serial inside the PSP reflected by the barcode that is scan at the cashier Can someone post their scanning barcode so that I can make sure they are all the same??
