It's not hard. If you don't like someone's price you can just move on. If you are honestly trying to help someone out with their pricing then you could send them a PM. If you feel you are the Campfire's consumer protection agency and honestly want to alert the folks on the classifieds to a better price then start a new thread. But if you feel entitled to something and are upset because you want to buy an item that someone has for sale but don't want to pay the asking price or you just want to stir up trouble for your own twisted entertainment, then by all means post on their ad.
These aren't rules of course but it's respectful behavior.
