For in-store pickup only, Micro Center offers the Jawbone Up Move Fitness Tracker in Black for $3.99. That's a buck under our Black Friday mention, the best price we've seen, and a low by $5. This clip-on Bluetooth device tracks steps, exercise, overall calories burned, hours slept, and quality of sleep. It's compatible with most iOS and Android phones via the free Jawbone Up app.
Knowing what to expect in advance can help you prepare for -- and adjust to -- life in your golden years.
