I'm just uber-paranoid about rebates, even though I've always received every one that I've ever applied for. Their whole purpose is to get people to pay full price for an item while offering the manufacturer the opportunity to get out of paying the rebate on a technicality.
The website didn't really give me a "print receipt" option. It did tell me that I would be receiving an email, which I should print (and I intend to print at some point from another PC), but I always take screenshots as a backup.
