Walmart offers the Gold's Gym 40-lb. Vinyl Cement Weight Set for $16.99. Opt for in-store pickup to avoid the $5.99 shipping charge and cut the price to $14.92. That's tied with our October mention, $23 off, and the lowest price we could find. It includes 40 lbs. of cement-filled weight plates, two 14" dumbbell handles, and collars.
