I paid for assembly by Handy.  The first guy assigned refused to do it.  Handy couldn't find anyone else.  When I called Wayfair to get the assembly refunded, they charged me for the whole thing a second time.  I would return it, but can't figure out how to lug a giant 80 lb box to my nearest UPS store. LOL!  Guess I'll try TaskRabbit.  Better be an awesome pergola.  ;-/
