Here in my county, there are several collection centers. They are for garbage, and also anything good enough to be reused. AND hazardous waste- paint, etc. You can stop by one any time and pick up anything you see in the recycle/reuse areas- free! That includes all the free paint you want! Also a great way to give away stuff you don't have the heart to throw out.
You name it, and I have seen it or gotten it there, furnished half my house. People toss good stuff all the time. I've even sold some of it.
I think Alachua County should be an example for everywhere else!
