My purchase experience from Wayfair was outstanding. Some of the boxes came in two separate deliveries, which posed a minor problem and some labor overruns. I called Wayfair and they took care of the issue beyond my satisfaction.  As for the Shearson Greenhouse, all the parts arrived in the boxes with some very good direction in an installation book. I had a foundation built and it sat on top of that. I am very happy with the greenhouse. My only concern would be the hinge for the window on top. It seems to only sit on the channel and I could not find a way to secure it from coming out if someone was to push on the window from the inside. If you are gentle, the window works fine, however if you use a little more force, the top of the window would come out of its channel. Not a big deal and all in all a great product for its price.
