Walmart offers the Gold's Gym 40-lb. Vinyl Cement Weight Set, model no. RSV-GG42-2, for $14.97. Opt for in-store pickup to avoid the $4.97 shipping charge. That's $5 below our June mention and the lowest total price we've seen. (It's a current low by $13.) It includes 40 lbs. of cement-filled weight plates, two 14" dumbbell handles, and collars.

Update: The price has dropped slightly to $14.77.
