I recently purchased a new graphics card (SAPPHIRE 100338L Radeon HD 6770 1GB 128-bit GDDR5) and there was a $20 rebate. My rebate came back today in the form of an American Express Gift Card for $20, instead of a check. This seems to be the new choice of payment for rebates now. Some prepaid cards charges a monthly fee if there is a balance. To avoid fees, I would recommend cashing out the prepaid cards in a form that would be useful to you.
