Amazon (AMZN) is testing an in-app purchasing service for Kindle Fire apps, further evidence of its interest in challenging Apple and Google's app stores head-on. Through the service, Amazon is targeting an in-app purchase market that IHS expects will reach $5.6B in 2015, up from $970M last year. Already, the company's Appstore for Android appears to be doing a much better job of monetizing apps than Google Play.
