Just another plug for the copags - I play maybe once a month, or even once every other month. Used the copags for the first time last night, and they truly are nice. With regular "plastic-coated" paper cards, they start getting bent and have creases in them after just a few hands. The copags yesterday went through about 4 hours of play, and look as good as they did when they came out of the package. Plus, they're washable too if you accidentally spill some beer on them.
I'm definitely a convert. Of course, this deal here is still awesome if you're getting some sets for kids or people that tend to misplace cards.
