Amazon is running a “Coinstoppable Promotion” where new customers can purchase 5,000 Amazon Coins for $25. That’s 50% off their regular price, which is the best deal on Amazon Coins that I’ve ever seen. It’s not entirely clear who qualifies as a “new customer.” My guess is it’s either those who have never purchased Amazon Coins or those who have never purchased an app from the Amazon Appstore. When you click the “Get Started” button on the promotion page, it takes you to a page with a claim button. If you don’t qualify for the discount, a message saying “something went wrong” will appear after you click the claim button, so you’ll know if you qualify before making the Amazon Coins purchase. This promotion ends November 30.
