Through 7/29 only, Bowflex lowers SelectTech 1090 Dumbbells from $599 to $359.40 via code 3DAY1090. Even better this code saves you $129.99 in shipping charges! This ties the lowest price we've ever seen for the pair (Amazon charges $298.52 for a single dumbbell). It is especially good for dorm rooms or small apartments as it replaces as many as 17 pairs of dumbbells in a compact unit. Each one adjusts from 10-90lbs in 5lb increments. This means you can switch from curls to squats to bench quickly while using the right weight for each exercise. Sales tax is charged in most states.
