As one of its daily deals, the Amazon Appstore for Android offers downloads of Voxel Invaders for Android
. That's $1 under the lowest price we could find for this Space Invaders-inspired game elsewhere. Deal ends March 20 at 2 am ET.
If you haven't claimed it yet, you can receive a $1 Amazon MP3 Credit for free with this download. (It can only be claimed once per Amazon account until December 31.)
