Costco's pharmacy generally also has excellent prices and makes them available through their website (for self pay or non-insurance meds, insurance co-pays are for you to determine). https://www.costco.com/pharmacy/drug-directory-main
+1 for Costco's pharmacy. In the rare occasion I need a prescription filled, its usually considerably cheaper than CVS or Walgreens. Plus, I'm prone to sinus infections and they have generic sudafed (real pseudoephedrine, not OTC) for just under $2 a box. Every other place in town is 5-10x that for the same thing.
