Amazon has just started running a new promotion that will earn you 500 Amazon Coins, a $5 value, just for watching a Prime Video on an Android device. Simply download the Amazon App for Android, select Amazon Instant Video form the menu in the upper left, and press Play on any Prime Video. You will be asked to install the Prime Video Player and will receive your 500 Free Amazon Coins within 72 hours of streaming a movie or TV show. Full details and instructions can be found on Amazon. Unfortunately, sideloading the Amazon app onto the Fire TV doesn’t work as the app crashes when you try to access Amazon Instant Video. You’ll have to use an Android smartphone or tablet.
