I'm in the process of getting rid of some stuff, that's pretty well used up, and in trying to sell it, my base line price has been determined by what I can get for it at the scrap yard, minus a few bucks for the effort it'd take me. (Cause I know that number, and I'm not going to sell it for less than that....)

My 79 International dump truck went straight to the scrap yard, because the junkyards I talked to wouldn't offer me what simple mathematics said it was worth as scrap.
