The Amazon Appstore is a fantastic alternative to the Google Play store and has been for a lengthy time. Consider their free app of the day, or the ability to reach the Amazon store when Google Play just won’t work, Amazon is there for you. Now, Amazon will be there for you in a new way as they introduce in-app purchase options for developers. Developers often use in-app purchases for things like buying extra items, removing ads, upgrades and more. This is great for both Amazon, developers and the user alike as Amazon continues to improve on their already excellent Google Play competitor.
