GameStop offers the ThinkGeek Star Wars BB-8 USB Car Charger for $14.99. Opt for in-store pickup to dodge the $4.99 shipping fee. That's $15 under our mention from two weeks ago and the lowest price we could find now by $12. Measuring 6" x 4" x 4", it features two USB charging ports, a moving head that rotates and makes sounds, three volume levels, and a 36" cable.
