Isn't it also against the rules to leave negative feedback for flakers? I have been seeing more and more sales posts with:
FLAKERS WILL RECEIVE NEGATIVE FEEDBACK!!!!
Generally, as soon as I see that I refuse to buy from the person. The item is not sold until cash is in hand, if you promise to sell it to everyone who inquires, your an idiot and are causing undue stress on YOURSELF. Several times I have had to cancel EMT's because the other guys payment got there first, last purchase I was beat by 8 minutes, I see that as totally fair.
