I thought Purse.io doesn't work with gift cards? I thought the process was a customer buys something on amazon via their credit card and then is paid in BTC once the item is delivered to the BTC seller.
From the Purse.io site:
How does this work?
8-50% discounts on everything at Amazon
We make entire Amazon marketplace available for bitcoin purchases. Spenders set their own discounts. Because Amazon ships to you directly, your purchase arrives quickly and the Buyer will never know your address.
Liquidate Amazon Gift Cards or buy bitcoin with a credit card
Purse allows you to purchase BTC quickly and anonymously with an Amazon gift card balance or credit card.
Haven't tried it personally yet, but eager to try it myself if I get some Amazon gift cards for Christmas.
