How to Buy Amazon Coins from Your Fire Tablet
To purchase apps and games, you can use Amazon Coins and save money. Amazon Coins are prepaid credits that reduce the price of apps and games by as much as 10 percent. You automatically earn Amazon Coins when you purchase certain Fire tablet apps and in-app items, or you can buy Amazon Coins directly.
Although Amazon Coins that you purchase do not expire, coins that you earn from purchases do expire 12 months after you receive them, and are used first when making purchases with them.
