Some manufacturer coupons/copay programs work a little differently than GoodRx—specifically the ones that you can only use if you're insured. Those ones work like this: HelpfulDrug costs $2000/month. Your insurance company will pay $1500/month, and wants to pass the remaining $500 onto you, but that's too expensive for you to pay. The manufacturers of HelpfulDrug see this and would rather not lose our on a deal, so they make you an offer: as long as your insurance pays the $1500 as promised, they'll tell insurance to waive $450 worth of your portion. You only pay $50, and the HelpfulDrug manufacturer still earns $1500, most of which is pure profit anyway.
