If you aren’t familiar with Amazon Coins, they are Amazon’s digital currency used to purchase apps, games, and in-app purchases from Amazon’s appstore. While most digital currency is a nuisance, Amazon coins have the unique advantage of always being less expensive than just using real money to make the same purchases. Case in point, you can currently buy Amazon Coins for up to 20% off. Amazon Coins come in various bundles from 500 to 10,000. The sweet spot is the 5,000 coin pack for $40 which gets you the full 20% off without having to buy too many coins at once. This Amazon Coin sale price is expected to last through November 1st. The same sale is also available in the UK, Germany, and Japan.
