I've had pretty good luck picking up Atrophied Attributes at the swap meet and flipping them on the psychic darkwave network. I spend a couple hours each day at the bins and you can find some real prizes. It helps to look for mistagging--yesterday I found Beautiful Smile tagged as Armpit Smell! But there's also niche markets that you need to be aware of, like #shockofwhitehair and #legtwitch #smellslikeyourdad, which you can really make good margins on. Not that I want to give away my secrets, but you really have to know what you're doing if you want to make any real money.
