Amazon sure loves giving away free apps, and today sees the start of its third Appstore promotion in almost as many months. If you're not following, Amazon's Android Appstore already offers a different piece of paid software for free each day. Lately, though, it's been discounting collections of apps for a limited time, like with the new "work, play & watch" bundle. In total, there are 27 apps worth around $135/£100 up for grabs until September 27th (this Saturday). It's not the most attractive buffet, but Riptide GP2, SketchBook Pro and the Swype keyboard are notable inclusions, with the most expensive being OfficeSuite Professional 7 (usually $14.99/£9.36) and the latest edition Merriam-Webster dictionary (normally $59/£34.44). Anyway, you may as well check out the full selection in case you spot anything you like; and remember, Amazon's Appstore isn't just available on its own hardware, but to anyone with an Android device and a few spare minutes.
