Walmart offers the Tone Fitness 20-lb. Hourglass Neoprene Dumbbell Set for $18.99. Choose in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $4 (most stores charge $30 or more), although we saw it for $3 less last month. It includes pairs of 2-, 3-, and 5-lb. weights and an A-frame rack.
