This is an interesting idea for donatable goods like clothes, but I lose the write off and I'm not sure waiting around for a pick-up is really more convenient than just driving the stuff to a drop off location myself.
The only real advantage I see here is getting rid of stuff that's hard to dispose of: car batteries (you know, cause I'm always throwing those away), poisonous or flammable liquids, medical waste (which I don't think I've ever had), etc... but I can't believe that is profitable cargo for them to haul away at $5/bag.
What am I missing here? Am I just the wrong demographic for this?
