Thank God for insurance.  I pay $15 through mail order for any prescription drugs for a 90 day supply.  I currently order Kristin's hydrocortone, florinef and depot-Lupron shots this way.  I had never thought too much about the hydrocortone or florinef, but I know the Lupron shots would be about $1300 each if I didn't have insurance and I get 3 of them for $15.
