I like CVS Pharmacy much better than Walgreens. I have ChampVA which pays 75 percent of the prescription cost. I can request refills online and select a new location where I want to pick them up. The only state that doesn't have CVS is Wyoming. Walmart Pharmacy is also cheaper and I have filled prescriptions on the road with them, but they aren't as friendly to travelers. The new location has to actually transfer the prescription to the new store and that takes longer. Walmart charges $10 for 90 day prescriptions on their generic list.
