You would make out better selling half cords. A full cord is one price, a half cord is more than half the price of a full cord and stacking is extra. My favorite is when people buy half cords and want them stacked, it doesn't take that long and you make more $$$.
I don't have many people pickup at all. The people picking up wood are cheap skates trying to save a buck. The people I deliver to are more willing to spend extra for stacking and/or tipping. I would rather sit on as much wood as I can until the really cold weather hits. Plan a route and haul two cords of wood into the city and stack out half cords or quarter cords (quarter cords are more than half the cost of half cords). Go back and do it again. Firewood is hard energy consuming, time consuming work, I have to be as efficient as possible to maximize my profit and keep my customers happy to return.
My delivery fee is already figured into the cost of the firewood, so it's always "Free" so if someone insists on picking up their firewood, they pay the same price as if it were delivered.
