My wife received a prescription for a new dementia med last month. CVS is our local pharmacy and the Dr's office electronically transmitted the prescription there. We are in one of the Medicare Advantage plans (Humana PPO) and the med was not covered well, resulting in a $386. Bill for a 30-day supply.
Today, after finding and registering at GoodRX, I paid $189. At Walgreens for her 2nd 30-day supply, utilizing the GoodRX discount. I had seen this same med as cheap as $117. At Walmart in previous weeks but apparently the pricing can change frequently- and wildly- as Walmart currently wanted $389.
So... use the handy search feature on the GoodRX website (where you'll get pricing), be ready to shop at different pharmacies and have your prescription in-hand so the pharmacy can give you an up-to-the-minute quote for your med. The savings really can be worth the additional trouble.
