If it is an Arrow brand greenhouse, commonly sold at home improvement warehouse stores, I wish you luck. I don't know if you have taken possession of the package yet, but be sure to open it and inspect the pieces before you leave the store (but it looks like you are having it drop-shipped to your home). I had terrible luck with a model that I ordered, with almost every major piece having unsightly dents or scratches. One factor was that the packaging did not hold up to shipping very well. I returned it to the store, did not take a chance on a reorder, and am currently building one myself.
