NoahM, I think that you are overreacting a little bit.
It's not because some people gave their opinion on your prices and that someone made a joke about it that you should leave... If you put your books for sale at your prices, surely you can guesss that some people wouldnt not agree with those prices, but then... they simply dont have to bid. That's it.
Good luck with your sales, and my advice would be for you to stay here longer. It's a really comfy place here, and soon you will also comment on other people's prices
