I’ve been waiting for this since last year — Costco only stocks these gazebo / pergola / "pavilion" seasonally.
Right now there is $200 off the normal price, plus another $300 off if you pick it up. There are 3 boxes that are pretty heavy, and about 8′ long. You could probably get them into a pickup but I used a trailer. Have not installed yet but it looked great in store, and the reviews are very positive. Also there are videos on youtube showing unboxing and how to install.
