Mark, I wrote an article on Win Cards a few months ago. I am not sure who is doing them today. They seem to come and go. I have about 30 different ones and not sure if any of these casinos are still doing them. I think the Lady Luck, Sahara, and Sunset Station are doing them now. The only thing a chipper cares about is getting the 10 or 15 chips that come with the cards for $10. They make good traders.

Ask at the casino cages or slot club booths. This is normally where they are sold. I will call the company that sells the cards and get an update on where they are using them now. He is a chip collector and tries to help.
