As one of its daily deals, A4C offers the refurbished Fitbit Charge Wireless Activity and Sleep Tracker in Black or Slate, model no. FB404, for $39 with free shipping. That's $48 under the lowest total price we could find for a new one, although we saw it for $3 less a week ago. It tracks your daily activity and sleep patterns to help you attain your fitness goals and features an OLED display showing caller ID and fitness stats. It's available in size S or L, although not in all size/color combinations. Deal ends today.
A 90-day A4C warranty applies.
