Brookstone via Rakuten Shopping offers the Fitbit Charge Wireless Activity and Sleep Wristband in Black, model no. FB404BKL, for $129.95. Coupon code "30OFF" cuts the price to $99.95. With free shipping, that's the lowest total price we could find by $20, although we saw one for free in winter with the opening of a new bank account. It tracks your steps taken, distance traveled, calories burned, stairs climbed, and sleep quality on its OLED display. It's available in size L only.
