Adding an anecdatum to the pile, my one and only experience with offering a (nice but unloved by the other occupant) chair for free got a response in the first 5 minutes who then arranged a courier to pick it up the following week. Painless.
Well I was giving away our coffee table. A very interested lady who was going to pick it up have held us home for better part of the day with half-hour postponements and then said it's too much trouble.
Relisted it for $20 and the next week it went painlessly.
I live at the end of a long driveway off a fairly busy road. I've had very good luck leaving a chair or old lawn equipment at the end of the driveway with a free sign. Gone within a few hours.
