These Bowflex EZ Pro Heart Rate Monitor Watches drop from $129.99 to $12.99 at Staples.com. Shipping adds $9.95, so to make this the best possible deal, add an item costing between $7 and $10 (like a Whetstone 25 oz. Stainless Steel Water Bottle 2pk) to get free shipping and save up to $3. However, with the shipping added, this is still the best price we could find for these heart rate monitors by $7 (See: Amazon, which only has 1 left in stock at this price before the price jumps to $89.99 everywhere else). These waterproof watches have an 100-hour stopwatch, 24-hour countdown timer, heart rate monitor and still show the date and time. Sales tax is charged in most states.
