Northwest-Outdoor via eBay offers the Fitbit Aria Wireless Smart Scale in Black or White, model no. FB201, for $74.99 with free shipping. That's $14 under our January mention and the lowest total price we've seen for a factory-sealed unit. (It's also a current low by $32. for further comparison we saw an open-box unit for $63 shipped three weeks ago.) This scale measures weight, body fat percentage, and body mass index; it uploads the information for use online or via Android or iOS app. Four AA batteries are required and included.
