Got a good deal on my GT5 preorder @ JB Hi-Fi Chatswood (Sydney) back in August and now that the game is out, scanned the receipt for a friend in VIC who successfully used it at a JB there.
The receipt on the left is the preorder/purchase receipt, and the one on the right is the pickup receipt. I've blanked out my name and the last 4 digits of my CC, but everything else is untouched.
NB: a receipt is not a guarantee, so I recommend talking to the salesman nicely (as opposed to charging in with guns blazing.) These receipts are all the proof that I can possibly provide, so sealing your own deal is up to you :)
Props.
Your receipt says "pricematch" on it, which store did you get jb to match?
