I have a problem with Microsoft and their claim filing process. I recently filed a rebate and sent it through the mail. The claim process is not the same had I filed on line. When you submit a claim through the mail you are required to supply additional product information. When you file online all they want is the barcode and store info. The only reason that I purchased the microsoft product was because of the rebate. Had I known that they have such a double standard when it comes to product rebates I would have gone with someone else.
