Jet.com offers the Oral-B 7000 SmartSeries Electric Rechargeable Toothbrush with Bluetooth in Black for $108. Coupon code "DEALS30" cuts it to $75.60. With free shipping, that's the lowest total price we could find by $32, although we saw it for a buck less two weeks ago. It features Bluetooth, real-time feedback on brushing habits, a Cross Action round brush head, and six cleaning modes.
