When I ordered mine in July Costco did not have any dealers in southern California participating in costco pricing program. X plan with Mustang club or Experimental Aircraft memberships are likely the best route to get the bes tprice. Or go to Grainger. 2% under invoice is nice! Could buy you a flight and gas homeWalk into the dealership with exact build you want and the "COSTCO" online build sheet in hand. They start at invoice and work down from there if they want your business. There are not a lot of COSTCO dealers out there (but they will notice your source!)
