I've had a lot of good experiences with my neighborhood's free box/buy nothing facebook group. I've probably had two dozen pickups and everything has been picked up usually in 1-2 days at a time convenient to me.
Ah, good to know. I guess I'm thinking back to my experiences on Craigslist. You get some absolute crazies for free things. I've had multiple encounters of people cussing me out, calling me names, and even death threats for a) not holding items, or b) not delivering items...that again, are free.
