Neighbors, friends, and relatives have given us:
+bikes for our kids
+clothes for our kids
+bedding: comforters, sheets, pillow shams
+dresser
+dog bed
+futon
Oh, and a CW gave me a bunch of clothes, so now I look presentable at work. :)
I pretty much take any and everything, so once you get known for that, everyone gives you their crap. If I don't like what's been dumped on me, I promptly donate to Goodwill.
Strangely enough, I've never accepted used appliances. We're on our 3rd home in 15 years and each time we move we buy new stove/fridge/washer/dryer/dishwasher. Probably anti-mustachian, but I like to have new appliances when I move...
