Not the op and they might know different ones but GoodRx is the one I'm familiar with. In talking with the pharmacy at Costco, it turned out to be probably cheaper to buy my son's prescription medicine out-of-pocket with an HSA than to do it through insurance. The reason I say "probably" is there are situations where you hit the insurance maximum per individual or for the family and then the cost for additional refills is zero. https://www.goodrx.com https://www.goodrx.com
