Blutek via eBay offers the Fitbit Flex 2 Activity Tracker Wristband in several colors (Black pictured) for $69.99. Check out via PayPal and apply coupon code "P20MEMDAY" to cut that to $55.99. With free shipping, that's $4 under our mention from four days ago (which included a $10 Kohl's gift card) and the lowest outright price we've seen. (It's the best deal now by $4, outside of the mention below.) It includes two wristbands (large and small) and tracks steps, distance, calories burned, and active minutes. Deal ends May 29.
Note: This coupon can only be used once per PayPal account within a single transaction. If you're a Kohl's shopper looking to save a little extra, it can still be ordered with $10 Kohl's Cash for $59.99 with in-store pickup.
