Walmart offers the Tone Fitness 20-lb. Hourglass Neoprene Dumbbell Set, model no. SDNHS-TN020, for $15.99. Choose in-store pickup to dodge the $4.97 shipping charge. That's tied with our mention from a month ago as the lowest total price we've seen. (It's also a current best by $7.) It includes pairs of 2-, 3-, and 5-lb. weights and an A-frame rack.
