Where I last lived, there was at least one charity that had free pickup by truck. Not on demand exactly, but they could take anything useful if it was boxed- or furniture. You could leave your stuff on the porch and they would shift it for you.

This seems strictly worse and very expensive if you want to get rid of any significant amount of stuff.

This one takes none-useful items too. The reason I want to get rid of the stuff is that it is not useful (unless you really want an old CRT tv or a case of broken computers, I guess).
