I know sometimes it's difficult to toss used things that may have some value left in them. But in many cases, (and this is a pretty good example of one of them), is why I do it. It's just not worth the hassle and risk of dealing with people you don't know over a few lousy bucks. Like trying to sell old junk at garage sales. You end up sitting out there all day dealing with these cheap, penny pinching chiselers, who think they're doing you a favor to be there, and offer you 50 cents for something you priced at a dollar. Just so they can replace the junk they sold last week at their garage sale, with new junk from yours.
If it's still in working order, I'll just set whatever it is out front on the sidewalk with a big "FREE" sign on it. It's usually gone within in a few minutes. I remember some years back I had an old, dirty propane gas grill I replaced with a new one. I rolled it out front. About an hour after I put it out there, this woman and her daughter were trying to load it into the back of a really nice, newer mini van. Before I could get outside and give them a hand, the whole thing tipped over, spilling the old, dirty lava rock all over the back of it. They laughed, got in and drove off. Her poor husband probably ended up having to clean it all up when he got home from work.
I do the same with old TV's, patio furniture, computer monitors, and or anything else that still works. If it doesn't, I'll make a dumpster run. You never know with people today. If they think you screwed them, and know where you live, God knows what they might or might not do. It's just not worth it.
