<< For those who ordered online, what receipt should we send in for the rebate? The only piece of paper that come with the item has a red "This is not an invoice" across it. If it's a staples rebate, then I wouldn't worry, but this is a different case. >>
I would print out the online receipt, either from their web site or the email you get. The packing slip is not valid for some rebates (like MS) because it does not list the price (or does it)? If it lists the price, I'd use that.
