Sorry I miss the bottom line of your posting. I am not sure what you mean. You want to sell NN chips for cash. I don't know of a market for this. If I buy NN chips from the casino it usually comes with some perks. So if you want to sell the NN chips to me I would compare it with the perks from the casino.
They are selling NN chips. We can buy from them and it cost us RM98 for every 100 NN chip. If I use them to play pontoon, I will have edge against the casino. Am I right?
May be I should call the guy to find out what the price is if we sell them our NN chips.
