Beach Camera via eBay offers the factory-refurbished Garmin Vivofit Bluetooth Fitness Band in six colors for $59.99 with free shipping. That's $11 under last month's mention of a new unit and the lowest total price we've seen. (It's also a current low for a refurb by $24.) This activity tracker uses past behavior to recommend daily goals to improve fitness. It also functions as a sleep monitor. A 1-year Garmin warranty applies.
