VA cal them and they will ship to where you are. Also like Edd505 said they will fill most meds for 90 days.
Wife now gets hers through CHAMP VA same pharmacy.The fill all her meds 90days at a time.
When she was getting hers though insurance where she worked and later Medicare supplement they only had certain pharmacies in the network.CVS They would fill only 30 days at a time, and she could get a medication filled one me out of home area. Next refill would require a new script there and when she got home. Really put a crimp in traveling for more than month after she retired.I kept telling her she could get them through the VA for several years.She could also have enrolled in VA and go her meds and if she wished, medical care at VA until she retired and went on Medicare including dental which she really needed and cost tn out of pocket and it would have continued.Wouldn't listen.
