Since I mostly hate my insurer and want to help them towards bankruptcy by extracting as much coverage from my fixed premium as possible, I have no objection to using these coupons if they'd help me and I felt like an expensive drug choice was better for me, though it's not come up for almost any drug I've needed.
Though I do need new epi-pens; maybe I should look for one while I still can!
