What no one has said is the reason for the "no selling" of chips requirement at the trading sessions. The dealers pay hundreds of dollars for their tables at the show so it would be unfair to them to allow others to come in and sell at the trade sessions for free. That said the chip police aren't going to get you if it takes $10 to make a trade even at one of the sessions. And like the others said, at the show you will see hundreds of thousands of chips for sale. Enjoy!
