Our maintenance meds go through Express Scripts, 90 day with 3 refills each year. We can designate an address if we are going to be in one place for a while as a temporary address, otherwise they get sent to Livingston, they send us an email when meds come in and we get them shipped to us where ever we are in 2-3 days. For short term we use Walgreens. Choice of both dictated by our insurance plan. Since we spend the winters in Arizona, we transferred to new physicians there and spread out our visits over the winter. October and end of March are our time to see physicians.
