CVS is good about having the medicine I need in stock (such as antibiotics) and having it ready for pick-up within a fairly reasonable time frame. Typically, I have had to wait no longer than 1 hr to come back by to pick it up. My one complaint is that they are very inconsistent on filling controlled substances. I have meds I take daily which are controlled and I truly need. The last straw was when they wouldn't even fill my rx on the day my doctor wrote it to be filled, insurance was okay to cover it, I had 3 days supply left, and I was leaving for vacation. My doctor had to call them, personally, and tell them they should fill it for me. NOT convenient at all! On top of that, this kind of treatment makes one feel judged unnecessarily. They could do better.
