This company does not know what they are doing. I have been getting an inhaler from my local retail preferred pharmacy. Express scripts has told me I have to start using their mail order pharmacy. I have a coupon for the inhaler that I can use at my local pharmacy that makes the medication free. Express scripts will not allow me to use the coupon and the medication cost more at their mail order pharmacy. Every time you call them it is a different story. This company is the worst.
