Staples offers the Jawbone Up Move Fitness Tracker in Blue Burst, model no. 44433SPR, for $9.99. Opt for in-store pickup to dodge the $9.95 shipping fee. That's tied with last month's mention as the lowest price we've seen. (It's also the best deal now by $3.) 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. Deal ends September 17.
