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.

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.
