Questions about the mail in rebate of BD movies from Amazon.com

[Aztec]

I got a couple of questions regarding the mail in rebate offer of the 5 free Blu Ray movies.

First, what EXACTLY is this UPC code Im supposed to find in the outside of the box of my PS3 when it arrives and mail with alongside my "mail in rebate" form?
And second, on the bottom of the form in the fine print it reads: "Store receipts must emanate from the same state as consumer address". Well this wouldn't be a problem if I had purchased my PS3 on a regular corner store but what about Amazon? Will I be rejected because I live in Texas and the receipt will be from whatever state Amazon's warehouse is supposed to be? What's that about? It would be stupid for Amazon to offer this and then reject all of the buyers from different states dont u think?
Please help me.

Thanks in advance for the help.
