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.
