Best Buy offers the Sphero Star Wars BB-8 Force Band for $49.99 with free shipping. That's $10 under our December mention and the lowest price we could find by $5. (Most stores charge $79.) It connects via Bluetooth to the Sphero Star Wars BB-8 App-Enabled Droid, and allows you to control it using arm and wrist gestures instead of through an app. Deal ends today.

Note that the BB-8 droid is sold separately.
