Amazon wants to give you free money, and you’re absolutely nuts if you don’t take it. Seriously… who passes up free money!?

Here’s how the promotion works: just head to this page and click the button to add the promotion to your account. Then buy $50 worth of Amazon gift cards and you’ll get a $15 credit on your account within a couple of days. That’s all there is to it! Add the $50 gift card balance to your own account since you’ll obviously spend that money with Amazon at some point anyway, and you’ll end up with $65. The one caveat is that the promotion is available only to people who have never bought Amazon gift cards before on the Amazon website. If you’ve purchased physical Amazon gift cards in a store at some point, that’s fine and you can still take advantage of the promo.
