Pontificating about the price someone else is paying for something (including a raffle ticket) is like the guy who pontificates about someone else’s call at a poker table. You may be the smartest guy in the room, but telling someone else what they should do with their own money is just annoying.
BUT (there's always a but), we are also trying to build and maintain a community here, and that means that we try to look out for each other, which includes sound opinions and advice on all sorts of matters, including current market value for chips. We don't want to see members being victims of fraudulent practices from within and without the membership, right? When we're dealing with hard-earned money, do we want reasonable explanations of valuations and somebody who's got our backs when it comes to advice?
