Pharmacies and benefit management companies have become very consolidated in recent years. And from what I've seen (which I'll have to be cryptic about since I don't want to accidentally reveal personal information about myself or anyone I know), it's not been to the benefit of consumers. Big evil companies that make money by screwing over sick people have been doing the 80s slash-and-burn consolidation thing where good companies are bought, existing customers are screwed over, and some small fraction of the company is absorbed into the greater machine. Buy a good company, deny people their medication, then make money off the difference until the customers leave for another company, then finally buy that one and repeat the cycle.<p>This means getting in there is going to be <i>very</i> profitable, and if amazon can get in there are use its existing scale they can get quite rich. There's now three benefit management companies that are in charge of altruistically deciding what medications you can afford. On the one hand, Amazon breaking up this pathological oligopoly would be good for consumers, but if it's really a market structure thing we run the risk of there still being on three companies, but with Amazon instead of CVS, ExpressScripts, or United Health.
