Bowflex has these Bowflex SelectTech 552 Dumbbells for $399. Even better, use code DFSTFBU9 to add the 3.1 Series Bench and 2-in-1 Stand for free. These benches go for about $308 if bought separately. The code also gives free shipping, a savings of $49.98. The dumbbells each adjust in 2.5 lb increments from 5 lbs to 52.5 lbs, so these dumbbells can replace a whole rack to save space. Sales tax is charged in most states.
