I just got a PS3 from Amazon.com and wanted to get the rebate. Amazon sent some sort of paper that looks like the shipping order. Does that count for a receipt? Rebate also wants the UPC barcode which I assume to be the POS bar code on the top. If I cut it off, I know I can't return the item but not sure of what else I would lose. In addition to above questions, also wondering what you need to send in if my PS3 ever breaks. Thanks in advance.
