Amazon offers the Fitbit Flex 2 Activity Tracker Wristband in Navy for $59.11 with free shipping. (It's available in several other colors for a buck more., Target, Best Buy via eBay, and several others have it for about the same price.) That's $10 under our Thanksgiving price and the best we've seen. (It's a current low by $14.) It includes two wristbands (large and small) and tracks steps, distance, calories burned, and active minutes.
