@Ainhisg I have not used Amazon pharmacy but have used GoodRx for more than a year.
I was using CVS pharmacy and discovered that CVS was much more expensive than other local pharmacies using GoodRX coupons.
What you do (you can experiment just to check it out now even if you might not need a refill yet) is get the information on your prescription....the exact name, dosage and the number of pills, etc. Put that information into the GoodRX site along with your zip code and the price for the pills will come up....the cost will vary depending on the pharmacy.
Usually there will be several pharmacies listed in your area with their prices. You can pick one, and the coupon will come up. If you want to make the purchase, you can either print out the coupon or send it to your phone (you can also take a photo of the image).
You then bring the coupon to your pharmacy when you want to make the purchase. They need to check the codes before they approve the price.
The last time I did this was early in the month. I decided to stop using CVS and go to Rite Aid since they were significantly cheaper.
My BP meds for 90 days would have cost me over $400.00 without insurance or a GoodRX coupon. If I had used CVS it would have cost over $150.00. By going to Rite Aid the cost was $33.00 but I had a one time deal coupon for $13.00! ...big difference!
I would check to see if prices are much less than CVS in your area even with your DH's company's deal with them. It's worth checking and by using a GoodRx coupon you are basically buying the medication without insurance.
How do they do it? I have no idea but I am curious how it is done.
ETA: To transfer a script I'm not sure if one pharmacy will do that for you....they don't want to lose business but you never know. What I do is call my doctor and tell them to send the Rx to a new pharmacy because of cost.
I want to add that I think it's all a very annoying game we have to play to get the best price for one's medication!
