Meds on the road.

The Walmarts or just about any other pharmacy chain can get prescriptions in their system forwarded to just about any of their stores that have a pharmacist. Of course that only works when you have one of their stores close by. For example in Valdez, AK, the nearest WM or other chain drug stores is only 285 miles close. Also, Canada will present some real problems. We use Express Scripts and get our 90 day renewals just before leaving. That requires some planning, but we've been doing it since 2006.

Have your prescriptions filled by Walmart pharmacy.

Since they have a national network, you can ask for a refill from their nearest branch. You have to call though first so they can verify it from the store where you have been getting your meds.

We switched to using a mail order pharmacy. We then just have our meds sent to general delivery at a post office near where we are or are going to be. It is a good idea though to call the post office and verify the general delivery options. Never had a problem doing this. With your refrigeration needs though you would have to time it pretty close.

I've had good luck working with my doctor and pharmacy to get bulk meds when we're going out of town. The tricky part is getting insurance to approve it. I finally worked with HR to switch over to Express Scripts to get 90 day supplies of all my meds.

You'll probably need more coordination that most because of your refrigerated meds. I would call your insurance in advance and request them to work with you to switch the FedEx delivery. This means you won't be able to travel spontaneously though, because you'll need to be in an exact location when they ship.
