I do rebates. My policy is, though, buy the item, send in the stuff for the rebate (following the instructions as closely as possible), then forget about it. Don't expect to see anything come back. Then, two months down the road, hey, $10 in my mailbox! When it comes (as it usually does) in the form of a prepaid AMEX/VISA/whatever, I do one of two things. I might do a PayPal "donation" to myself in the amount of the card. Some fees, sure, but I don't have half a dozen such cards laying around with a few cents on them. Or, I'll buy an Amazon (or Newegg, or whatever) gift card for the amount. Full usage, no fees.
PayPal says they support prepaid cards now, but what that entails I haven't looked in to yet.
