Sam's Club only has a few wood sheds available. Costco offers a significantly better selection of wood sheds than Sam's Club. For an 8-by-6-foot wood shed, the Gardena model with double doors on the long side costs $1,999 at Sam's Club. A similarly sized shed costs $1,699.99 at Costco. It's a Yardline model that has dual doors on the front with small windows at the top of the doors. Both prices require a DIY installation.
