Keep in mind $100 is the retail price, not the wholesale price (which is what's plotted on the above graph). I do not know what the current wholesale price is for a generic epi-pen.
My point is merely that the price is trending back down now that there's competition. And again, with insurance it's effectively free for most people - either through private insurance or medicaid.
