ZTE Awe Android phone, Today only, the Awe is $39.99. That's half off the regular $79.99 price.
The Awe is a bit basic but gets generally good reviews for performance thanks to a 1.2 Ghz dual-core processor and 1 GB of RAM. The four inch screen has a a respectable 480x800px resolution and the Awe runs the relatively recent Jellybean version of Android. The phone's camera is it's weakest point. It does have an LED flash and auto focus, both rare on entry level phones, but the camera is slow to launch and slow to focus and picture quality is mediocre. As long as photography isn't your primary "focus" the Awe is hard to beat for forty bucks.
The Awe is notable for being the best of Virgin's current phones that can be swapped on to a grandfathered $25/month account without causing a forced upgrade to Virgin's current $35/month plan. For this to work you must already have a grandfathered plan and you have to switch phones online, not by calling customer support.
