As one of its daily deals, A4C offers the refurbished Fitbit Charge HR Wireless Activity Wristband in Black or Purple, model no. FB405, for $49.95 with free shipping. That's $17 under the lowest total price we could find for a new one in any color, although we saw a refurb for $5 less in January. Features include continuous heart-rate monitoring, step-, distance-, sleep-, and calorie-tracking, GPS, time and date display, and wireless sync via Bluetooth with supported computers/smartphones. It's available in sizes S or L. Deal ends today.
Note: A 90-day A4C warranty applies.
