I'm a Kaiser Permanente patient. It's the greatest plan in the world IMHO. I pay $20 copay for office visits, $50 for ER visits, $250 for hospital stays, and $20 for generic 3 month prescriptions. I can get some of the generics at WalMart for $10 for a 3 month supply, but it would be a hassle to go out of KP with written prescriptions.
