For in-store pickup only, Micro Center again offers the Jawbone Up Move Fitness Tracker in Black for $3.99. That’s tied with our mention from three weeks ago as the lowest price we’ve seen. (It’s the best deal now 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.
