As one of its daily deals, CowBoom offers the SYNC Burn Fitness Band in Black/Red, model no. SP2227RE, for $19.99 plus $5 for shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's a current price low by $38; most places charge $80 or more.) It tracks calories burned, steps taken and distance traveled, and features a heart rate monitor and ECG accurate data. Deal ends today.
