I pay $5 (co-pay) for 300 GENERIC tablets. I could get a 90 day supply (900) for $10 -- but, with the humidity problems we have in Tennessee -- I prefer to get mine "fresh" every month (LOL). As it is, my pharmacy puts about 10 desiccants in each bottle of tablets.

Name brand would cost me $75 per month -- $100 for 90 days.
