BuyDig via eBay offers the Garmin Vivosmart Bluetooth Activity Tracker in Black or Slate, model no. 010-01317-10, bundled with the Garmin Heart Rate Monitor, model no. 010-10997-00, for $69.99 with free shipping. That's tied with our mention from last week as the lowest total price we've seen. (It's a current low by $25.) The Vivosmart tracks your steps, distance traveled, calories burned, and time of day and features notification and display of incoming text messages, emails, and calls. It's available in S or L sizes, although not in all color/size combinations.
