In my personal experience, the goodrx "coupon" for my drug was $30. Sure enough, at the pharmacy, I was charged $30. But if I use the same coupon the next month, the price is magically $57. I could print out a new coupon every time, but the process with the pharm tech to change to a different "drug card" (which is what they see it as) is nearly a 5 minute process. By contrast, my state offers their own group drug card, and the charge is usually around $45. It might go up or down by a few dollars every 6 months, but that is it.

Typically a pharmacy will enter into a contract with a PBM and the PBM will reimburse the pharmacy for each drug at a set amount. That amount does include a dispensing fee, but the pharmacy can also make money off the margin between acquisition and reimbursement.
So if a months supply costs the pharmacy $30.
The PBM might pay $23 for the drug, $2 dispensing fee and tells the pharmacy to collect a $10 co-pay ($35 total).
Pharmacy makes $5.
However, what I've heard is that it's never that simple. PBMs are constantly trying to pay as close to acquisition cost as possible and when you have multi-source drugs (generics), they often just pay the lowest price.
So I've heard from pharmacies that some drugs have a 50% margin and other have a -20% margin. The PBM tells them it "all evens out" which is BS. The PBMs also have DIR fees, where a couple quarters later they claw back additional money, again arguing that the prior reimbursement was too high. The PBM model is really trying to squeeze pharmacy margins as much as they can.
There are companies known as PBMs (Pharmacy Benefits Manager) whose sole purpose is to negotiate rebates and group discounts on behalf of insurers and employers.
GoodRx operates as PBM at scale or more exactly as an aggregator of deals from PBMs + Pharmacies. The pharmacies pay them because they drive volume and the PBMs pay them because they help to lower the cost of their medication programs which is one of the reasons they exist.
It's the same model of a coupon website.
All the big insurers have their own PBMs now so I'm not bullish on their business model lasting. Insurance companies hold the trump cards as they are the ones collecting the premiums and have the money. There's no reason for any of the big companies to give up margin to GoodRx. Maybe some of the smaller health plans might have to make deals with them.
There’s really no margins in paying for medications. This is always a red number for the insurance.
This isn’t accurate. Insurance companies have legal fixed profit margins as a percent of spending, so they want this to be as high as possible. This creates a vested interest in both maintaining high prices and spending.
