Amazon is running a new promotion which gives you 550 Amazon Coins for free (a $5 value) when you purchase the Fire TV Game Controller. This is a great deal because the game controller is already on sale for $39.99, which is down from its regular price of $49.99. The combination of the sale price and free coins makes this the best deal ever for the official game controller. Unfortunately, click the terms and conditions link on the promotion page takes you to information about Amazon coins, and not this specific promotion, so there’s no way to know how long this deal will last. After purchasing the game controller, your 550 coins will automatically be added to your account’s coin balance within 48 hours.
