Our prescription insurance is specifically with CVS. We can get 90-day prescriptions either by mail or at any CVS store. We have a local CVS, and most often while traveling we try to find a CVS store. But before we leave for 3-4 months, we have been able to get a "vacation override" from the insurance company to get prescriptions filled earlier than scheduled, before we take off on a trip. Our local CVS store first tries to fill the Rx, it gets kicked back as too soon to fill, then either the store or we call the insurance company to request a vacation override telling them we'll be gone traveling for such-and-such length of time. I think we can only do this vacation override a certain number of times a year, like maybe twice.
