I got my new one in the mail yesterday. Instead of giving you $50 like last year, it looks like this one will pay $25 if your copay is $50 and pay $50 if your copay is $75. So at best, you'll still have to pay $25 and possibly more if your copay is >$75.
Also, it is only good for six fills and it expires at the end of June. I would assume that means we'll get another one in June, but the card says it's the 2011 savings card, which makes it seems like that's it for the year. Hopefully there will be two 2011 savings cards!
