I go through spells buying/selling CL and Armslist. The last time I moved I tried selling a bunch of older furniture, electronics, collectibles, and such. I priced the stuff really low, wrote good listings with 3 pics (most you could do at the time I think), and was trying to just spare the landfill and hopefully get a few bucks for my time. The derp was amazing. What was more amazing was how much derpier it got once I got so tired of the derp that I decided to just give the stuff away.
Example: a nice (I.e. not out of a box) computer desk. Worth $100 easy, originally tried to get $20. E-mails come in with "I'll give you $10 if you bring it to me", or ""are there any scratches on it". Okay, can't get any buyers and I'm moving next week, so I list it for free. E-mails come in "can you bring it to me", "can you hold it until the end of the month", " do the drawers all work", etc. I finally do the curb alert thing and drag it out to the street, continue to get moronic emails. Thankfully one of the neighbors comes over and asks how much I want for it. I told him it was free as long as he took the monitor that was sitting on top of it. Never would have believed it would be so hard to give stuff away.
