You don't need a reciept. However, I'm am still waiting for them to tell me that my copy of Rock Band has come in to Deerfoot Meadows. Even though my buddy went in over a month ago and bought one right off their shelf for me.
Not to mention that when I called in to call them on it, they lied and said they didn't have any in yet, and have lied a few more times to me. I'd ask for my $10 pre-order back, but the $10 is almost worth the entertainment of watching how long it will take (if ever) for those idiots to give me a call.
I would laugh if they called in two years time to say they finally got it in for me.
