GeekDeal via eBay offers the open-box Fitbit Aria Wi-Fi Smart Scale in White, model no. FB201, for $72.95 with free shipping. That's $2 under last month's mention and the lowest total price we've seen, outside of refurbs. (It's $31 under a new one.) It features body fat percentage tracking, integration with Fitbit.com, and support for up to eight users.

A 6-month warranty applies, but it's unclear who backs it.
