ProElectronics Distributing via Rakuten offers the Fitbit Alta Heart Rate + Fitness Wristband in Black for $99. Coupon code "SAVE15" drops that to $84.15. With free shipping, that's the lowest price we could find by $13, although we saw it for $80 with a $15 store credit on Black Friday. It tracks your daily activity, heart rate, and sleep patterns and features an OLED display showing caller ID and fitness stats. It's available in sizes S or L. Deal ends March 6. Note: This coupon can only be used once per account, with a maximum discount of $60. (You must be signed in to use it.)
