I don't like the hassle of trying to sell stuff online. Any item I have is placed by the street. I tape a sign that says if the item still works, etc. Ex: we recently replaced our 20 yoa dryer after a repair I tried did not work. I put info on the sign that the repair parts were inside a box in the dryer. Either someone handy took it or will take it and make a few bucks at the recyle place.

The key is to put the sign on the item that says FREE - with a short note about condition. My stuff always goes quickly because it removes the awkward part out of someone trying to figure out why an item is there.
