I've only been to the last two conventions despite the fact that I've been collecting and in the club for over 20 years. At those two conventions, I did not see anyone setting up shop in the trading room to sell chips and I did not see any money change hands but I do not doubt that it happened in the past, hence all the heartburn. In all the trade sessions I've been to, the club has had a monitor (usually Reggie) watching out for cash sales so that may be the way the club addressed it. If there is any money changing hands it is peanuts. Everyone needs to consider that those of us who choose to attend the convention are there to have FUN, meet and see fellow chip collectors, and BUY, BUY, BUY!!! Hope to see you there one day! Cheers!
