I spent a lot of time researching gazebos - both locally and online. Usually I would be worried about making such a large purchase online, but I know Wayfair stands behind its products and has a most excellent customer service department. They even contacted the manufacturer to get an answer for me after my purchase arrived.
It came much sooner than predicted too, which was a pleasant surprise! The delivery men were most accomodating. 
The whole process was just so positive.
