My previous insurance just wouldn’t cover any long-term prescriptions if I didn’t fill it through Caremark on a 90-day supply. It was so annoying to deal with them. My regular pharmacy is two blocks away, if there’s an issue with insurance or something, they give me a call and have generally been pro-active. Caremark would just sit on their hands until I realized it was weird I hadn’t gotten a shipping notification, only to go “Oh, yeah, when we got this prescription we specifically requested you send through us, we decided there wasn’t enough info to determine if you need it, so you need to call your doctor and tell them to call us.”
