Starting on December 24th and running through the 28th, anyone who downloads an app or game using the latest version of the Amazon Appstore client will get a $5 credit to spend on Appstore content. It doesn't matter if you've had the Appstore installed before or not – just get the new version and you're good to go. The app you download to trigger the deal can be free – including the free app of the day, which Amazon is going to be pushing hard this week with big names like Angry Birds Star Wars II and Quell Memento.The free Amazon money is only for use in the Appstore. You can use it to get paid apps and games, or to make in-app purchases.
Step one: Download the Amazon Appstore for Android.
Step two: Install to your Android device.
1. Android requires that Unknown Sources be enabled for non-Google apps, like Amazon Appstore, to be installed on your device. To allow, go to Settings, then Security or Applications (depending on your device.) Once there, check the box for Unknown Sources.
2. Find the download in your Notifications. If you don’t see the Appstore Installer in your Notifications area after download, go to your apps and tap Downloads.
