Walmart offers the Air Hogs Robo Trax Remote-Controlled All-Terrain Tank with Robot Transformation for $24.99. (Amazon charges the same with free shipping for Prime members.) Choose in-store pickup to avoid the $5.99 shipping fee. That's $12 under our December mention and the lowest price we've seen. (It also beats our Black Friday mention and is the best deal we could find now by $15.)

It transforms from an all-terrain tank to a self-balancing robot. Features include two missile bays, sound effects, lights, a 2.4GHz remote control with 100-foot control range, 6 missiles, and rechargeable battery. The remote requires three AAA batteries, not included.

Update: The price has dropped to $22.99.
