I had a similar situation with my mail order pharmacy. Ordered a 90-day supply of maintenance medication, was charged brand rates against my deductible. They dispensed the brand rather than the generic. Asked why, they said, well, we have a deal with the company, you get brand drugs at the cost of the generic co-pay! They neglected to understand that some of us don't have co-pays for Rx, and pay the actual cost. Solution? Go to Costco, get 30-day subscription, pay pennies per pill.
