I would be interested to know this too. I pay $50 for 90 10mg tablets of the generic kind.
I have been looking for any kind of cheaper way to go.
You might be able to get into a prescrition card program, or there is some prgram with Novartis where they give you very cheap prescriptions.
Or try freemedicineprogram.com
My next thought is driving to Canada to fill my script cause it is around half the price there. But I am fairly close to canada, probably not the situation for you.
