Dave Winer shares that he was surprised that one of his drugs is $400 per month. Just last week I went through the same thing. A drug that I've been taking retails for ~$400 a month. That is over $13 a pill. Every night I take a night out to the movies (well, in 1995) and my insurance pays for it. Online you can find it from US pharmacies for as little as $325. Canadian pharamacies are selling it into the US for $150.
With a wife who is a doctor and a pretty good understanding of economics, I understand why this discrepancy exists. I've also been to Ruth's Chris and El Gaucho on the drug companies dime. The drug companies are setting themselves up for a peasant uprising.
I didn't notice because the health insurance plan has no copay. The pharmacist kept telling me how lucky we are to have such great insurance.
