To take away from this, I've found that people who search for free stuff on Facebook tend to be painful to deal with - not turning up, leaving parts of the product they don't want behind for you to dispose of, jumping on products they don't even want just because it's free and just generally being ungrateful arseholes.
You're much better off selling something at a price below market value if you want it gone cheap to someone can use it.
At the end of my posting I ask people to write me back with an exact date and time they will come over, a number so I can text them the address, and one of their personal or professional goals. If they don't write all 3 then I don't respond. It works pretty well!
I've had good luck requiring someone to make an appointment and pick up free stuff. No need to deal with money, they still get the stuff for free and seems to cut out the time wasters.
I’ve used BuyNothing many times in my city. I’ve mostly used it to give things away, but have scored some great camping gear too. It’s been a very positive experience compared to listing free items on Facebook or Craigslist. People on BuyNothing have been responsible and grateful.
