It would help to acquaint yourself with the rules and customs of the forum instead of attempting to overrule them with your own.
Discussions with a seller over their item regarding price are best served in a respectful PM. That way you're treating them with the same respect in their space as you would want for yourself.
Fair enough. And I do agree with that in most cases. However, when something is priced 200% above market value, then I have no qualms about posting about it publicly, unless the forum rules say that I shouldn't.
Anyways, I'll leave you guys to your discussion. I'm only here to look for good deals on comics.
That being said, I am happy to follow the rules of your forum, if non-discussion of pricing is in your rules.
