Express-Scripts is, hands down, the worst pharmacy I've ever had the displeasure of dealing with! Frighteningly incompetent and surly, they have become so bad, in fact, that I've decided I'm willing to pay EXTRA to fill my prescriptions a local pharmacy. If you are ever encouraged to "save money" and or "have convenient home delivery, " run away! Far, far away. Express-Scripts will send the wrong medication, or will delay sending the correct one after you've completely run for it of it and not authorize an override at a local pharmacy, they will try to blame your doctor for everything, will demand repeated authorizations, and basically try to kill you!
