Craigslist helped me give away a (working) TV today. I love the freebies section.
Some freebies I've found on Craigslist: clothes, toys, and even the chair I am sitting in. One's trash is another's treasure, or so they say.
I know people make a profit in the cars+trucks section. I purchase 2 autos listed there. But I hope nobody uses the freebies for profit.
Give to someone who has less than you, that's my motto.
