According to various sources, Amazon is now offering $5 gift credits to anyone who manages to download an Amazon app —even free ones— before December 28, 2013.
There are a few catches to the holiday spirited offer. First, the rules apply only to those who own an existing Android device. Second, all downloaded/purchased apps have to be acquired through Amazon’s own Appstore app in order for the $5 gift credit to actually work.
The credit, once obtained, can be used on virtually anything the app store has offer, including digital games and in-game purchases.
The app store itself, notably, will also begin promoting free games on a daily basis, so be sure to check it often. According to CNET, some of the more noteworthy titles that are already being offered for free include Piano Master: Christmas special and Angry Birds Star Wars II.
