I've had a lot of success with Cost Plus Drug as well.
They have cleverly, although transparently, applied the fee model to prescriptions. You see one price on their page, but when you get to checkout the total price inclusive of everything might be more expensive than your local Walmart.
Their marketing is incredibly effective, though. I can’t believe how many people think Cost Plus must be the cheapest option who are then shocked to discover the same prescription is $4 at their local Walmart.
