Even as a seller I like the fact that if I was overpricing someone would say something because I like to think I would provide a fair deal and it's against the spirit of the community to rip people off. If I perhaps felt like it's worth slightly more, there's always fleabay...
having said this, do you not know when you're over pricing something?
i personally prefer to discuss in a pm to the seller so that crappy responses stay off the thread.
magnello can ask whatever he wants for his items, make an offer if you think it's overpriced or move on.
