Amazon has another app-related promotion for those deep into the Amazon app ecosystem. They have a 20% off sale on the purchase of Amazon Coins. The sale price is already factored in, so, for example, $80 gets you 10,000 Amazon coins ($100 equivalent). The Coins can only be used to purchase apps, games, and in-app/in-game items. They cannot be used for other purchases at Amazon but you can give them to friends… There are over 1000 for-pay/premium photography apps over there.
This promotion should not be confused with the recently launched Amazon Underground.
Personally I am not a fan of made-up digital currency, but thankfully for the rest of the universe, I am not the Czar of the Universe
