Goodrx makes money by exploiting the PBM system (which I'm in favor of them doing, to be clear.) If it becomes too popular then something will change in the pharmacy-PBM contracts or the goodrx coupon margin will naturally narrow as they become "the price" and their margins on the rebate sharing narrow as afforded by transaction volume. Goodrx is great, but it doesn't save money for the majority of insured (for the half of the country on better-than-average plans) and it doesn't bring down costs nearly as much as you'd want for expensive medications. Cycling manufacturer's coupons for expensive medications can match or beat insurance copays when Goodrx won't. (And you'll increasingly find some insurance actually apply a manufacturer's coupon rather than cover directly. I had this happen recently with a 90-day supply of Freestyle Libre 3.)
