Yes, as Bruce has said, https://www.freecycle.org/ is likely the organization to which Uncle DaveO referred.

Generally, it takes time and experience to learn the accepted practices of a new culture. As for aggressive haggling, buying for resale and therefore wanting to pay nickles for reasonably priced items- a friend has an effective strategy. When rudely asked for a better price or offered an absurdly low price, he quotes a final price higher than he had listed. When polite, friendly people negotiate, he's a peach without being railroaded.

If I'm selling, I need to make some cash. When I don't need the cash, I donate the item wherever it will be helpful. I know gnu is effective and proactive in both situations.
