First let me say that I love Costco however I do not love their pharmacy. There is no level of service at that place. If you call in a prescription and they can't fill it, they don't let you know until you show up to purchase your prescription. I have moved my prescriptions to Walgreens where you can get a very good level of service at no cost due to their systems. I get automated phone calls when my prescription is filled, I can set up a reminder each month and have it filled automatically, and when they don't have my particular medicine they will call all over the place to find it for me. The folks at the Costco pharmacy act like they couldn't care less if you don't have your medicine. The only time that I may use this pharmacy is when it is for something that is not covered by my prescription insurance & I guess the few times i will use them is worth the few dollars saved, like on vet meds.
