They spend on fuel, expended upper-stage rocket, and maybe fairings? Do they retrieve fairings? I know they had a boat to chase and catch them, and gave that up. They could make them float, with a beacon, and drive out and get them, and wash the salt off. I would think so, but back when they still chased them, I was viciously downvoted for suggesting that would be cheaper.
