> When I go to buy a car, I haggle with salesmen and test drive cars, all for free, before I choose one. When I am condo shopping, I go see many buildings, and many different agents give me the sales spiel, free, before I choose which condo I want and provide the commission to that realtor.

Yeah, but you're viewing pre-built cars and condos, rather than asking for a completely original work to be created from scratch before you buy.
