Express Scripts delivers through the mail from one of their big distribution centers. We also use them for all of our maintenance meds (required by our insurance company to save money) and they shipped them out to our Livingston address (or to a temporary address if we are going to be in one spot for a while) and the shipment has a tracking number so I can tell when it reaches Livingston and then I request our next mail shipment. We get our scrips written for 90 day supplies with 4 refills so we can go a whole year between checkups. For short-term medications we use Walgreens.
