I am still assembling this shed and like it so far. The doors are next. However, Wayfair should know that there was a part substitution error. The four roof support spars comprise two pieces; .. 28 and .. 28a. The 28a pieces were missing, but four extra 28 pieces were included. I was able to drill and connect these to use as substitutes, but this modification added time and difficulty to what was otherwise an easy assembly process. I will keep the shed, but would appreciate some kind of credit for my trouble, Replacement parts are of no help at this point.
