Today only, Northwest-Outdoor via eBay offers the Fitbit Aria Wireless Smart Scale in Black or White, model no. FB201, for $66.95. Apply coupon code "CFLASHSAVE15NOW" and pay via PayPal to drop it to $51.95. That's $15 below last month's mention of an open-box unit (this one is new) and the lowest total price we've seen for this scale in any condition. (It's the best deal now for a new unit by $50, although most stores charge around $130.) 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.

Note: The coupon can be used once per PayPal account.
