Harbor Freight has the Haul Master 1000 lb. (12" X 18") Moving Dolly on sale for $10 or use the 20% Off Coupon code below to order online and get it for $8. Unfortunately code is only good for first item. Shipping is $7 flat rate. I ordered several to make the flat rate worthwhile and got the free work light as well. If ordering online use codes below for discount and free LED Work Light.
