You lost nothing so you werent actually scammed.
That actually isn't true. I went to the store and bought this for him, I already have one, I didn't want 2 and I think i lost the reciept. So I actually DID get scammed in a sense.
Well then that is called a lesson learned. never get stuff for others till they pay you first or you get their trade or at least keep the receipt. All of that is your fault.
