I happened to notice these deals when I went on Citi easy deals. If you have a Citibank credit card. log onto citieasydeals.com. go to gift cards. There are many other store gift cards (target, home Depot..) The amazon gc is a limited time offer so not sure how long it will last.
**Citi Easy deals only works for AT&T/ Simplicity / Diamond Preferred
Edit: Apparently you need to spend over 100/year on your Citi cc to be eligible
