BUYERS, What Issues have you had with Sellers and Listings that Prevent you from Buying?

I just sold a pair of headphones here in less than 8 hours.  Most of my other sales have happened within 2 days.  I price the items right and am willing to further negotiate.  I never charge any fees and am very generous on the shipping.  I never respond to the tire kickers.  You know the guy who offers you 900 bucks on the asking price of 2K.  

Perhaps they should clean the dust off the equipment they are selling.  When I see that even if I am interested, I’ll pass.  If they can’t even to be bothered to keep it clean, chances are they just don’t care.
