I know some people who do the Canadian pharmacy thing, and the primary win is in new drugs where generic versions aren't available. The savings can be huge.
Although we have insurance, Irv, we chose the option that has a prescription rider that ONLY covers diabetic and chemo type medications. Going to 'full, prescription coverage would have resulted in additional premiums of something like $300 a month additional. Since the medication we take is largely generic or recently OTC, we didn't opt for full coverage.
Even with that, I was annoyed at the ~$55/bottle charge for the eye drops. I went to the website, GoodRX, typed in the name of the drops, and found that I could get it for $15. That's a hell of a savings. I heartily recommend checking it out. It will give you a list of places near you along with the prices. Signing up with them will allow you to get alerts when the prices change or if a better price is now available at a different pharmacy.
I don't think it's well known, but your pharmacist is obligated by law to tell you if your prescription can be obtained for less elsewhere if you ask. They're not obligated to tell you on their own though.
