The fact that the only thing a buyer has to really go by as far as the seller they are thinking of buying from is their feedback, you would think that E-bay wouldn't have F'ed with it but now they've screwed it all up with the "no negative" feedback rule!
I hear ya on lazy buyers. I've sold a few things on ebay so my trans count is low but it would be nice for them to leave positive feedback. It takes, what, a minute to do?
