For all the different meds that I take, I visited one dozen places. I got the prices first with out any discount, then four discount cards. The one of this concern is GoodRx for all my meds, some actually cost more and the rest of them saved less than 10%. The other three cards saved on average 40% or more. My word of advice, tell everyone you know that GoodRx is not even worth the time to get it.
