Love Costco, have been a member for 15+ years now.  A word of caution, you may want to count your pills before leaving the pharmacy.  Since May 2014, now Sept 2014 I have had three prescriptions shorted by several pills.  Picked up my latest prescription less than an hour ago, came home, and this one was short.  Dang, going back right now to have them get the quantity right.
