IMO you should use purse.io, they allow you to fill gift list orders and the person receiving the gift list would pay in bitcoin. Their site has an escrow system in place that can monitor the status of the order and will automatically credit your account as the order is delivered.
I thought about it, but isn't it require send items from amazon? I'm not sure about it, but i think it's impossible to buy gift cards with gift card.
Best way to sell an amazon card would be to first prove that it wasn't carded, and once you prove that it has been obtained legitly, next step is to agree to a price, youd be willing to sell. Good price to go with is around 85-90%. 70-80% should allow you to sell it fast enough.
They aren't carded, most of them comes from exchange miles and points from rewards program (such as Amex, Alaska Airlines, Hilton HHonor, etc) - people who travel a lot will rather sell those points instead of waiting 2 months (sic!) for reward from program. Not sure how can i proof it, but i'm open for advices!
Caga - same as above.
