Found the following link after hearing something on the news the other night:
Not an insurance plan, but you can price and pay for your scrip on their site (no charge to join) and go pick it up .... at your pharmacy. We are just turning 65 and rarely use prescriptions, so went with a cheapo high deductible part D. For the few things we occasionally use, this is far better than using the "insurance." Yeah, I know it doesn't apply to the insurance deductible, but unless we start gobbling pills we're far better off.
One example; pay retail at Walgreens $85. Pay Blink $14 and pick it up at same Walgreens. Anyway, you may want to check it out. I don't see a downside as it's no fee, not buying from some mysterious warehouse, can opt out on case by case basis.
