When I ordered a convertible gas grill my assumption was that it would  come with whatever was needed to convert to gas or propane. I was disappointed to find that it was set up for propane, with no mention of convertible in the instructions. I called to complain and was told that is was convertible, but the conversion kit was sold separately. I thought that the description of the article I ordered was misleading, Customer service agreed, and through discounts were able to get me all that I required with no additional expense to me. I consider that to be excellent service. This was my first purchase from Wayfair, but certainly won't be my last.
