Ending today, Groupon offers the Garmin Vivosmart Bluetooth Activity Tracker in five colors (Black pictured) for $99.99. Coupon code "JUMBO3" drops it to $89.99. (Amazon charges the same in Black/Large and Berry/Small.) With free shipping, that's the lowest total price we could find by $5, although we saw it for $30 less on Cyber Monday. It tracks your steps, distance traveled, calories burned, and time of day and features notification and display of incoming text messages, emails, and calls. It comes in size S or L.

It's also available in select sizes bundled with the Garmin Heart Rate Monitor, model no. 010-10997-00, for $129.99 before the coupon above and $116.99 after. With free shipping, that's the best deal we could find by $2, although we saw it for $27 less a month ago. (Most retailers charge at least $125.)
