Bowflex Catalog offers its Bowflex TreadClimber TC20 Cardio Machine for $3,299. Plus, coupon code "FIREWORKS" drops the price to $2,999 and nets free shipping; it also bags the Bowflex Boost. That's $1,260 off for these two items and the lowest total price we could find, although we saw the TreadClimber bundled with a different item for $100 less in December. The TreadClimber features a maximum speed of 4.5 mph, five monitoring functions for speed, distance, time, calories, and heart rate, longer foot treadles, and supports two users. The Bowflex Boost logs calories, steps, distance traveled, and sleep with a purported 11-day battery life.
