Amazon has just released an in-App purchasing API for PC and Mac Apps. Game developers should win big. This closely follows its Kindle ebook commitment to extending products across platforms.

The roll out for in-App purchases in games was likewise first available to Kindle Fire and Android developers last April, a precursor to this announcement.
