You're ripping them off because you're selling it for more than you bought it for. Go over to the TGR forum and everybody tries to help each other out by selling things either for what they're worth or what they bought them for (whichever is cheaper). Trying to make a profit off of another guy that is struggling to afford to ski isn't very cool, and that is why there are rules against it. It's stupid that there has to be rules, but unforutnately there are people that still try to do it. So think of somebody besides yourself and pass on the good deals to people who need it. If you want to be an ass, sell stuff to gapers or tourists, that's perfectly acceptable.
