But maybe investors shouldn't get quite so excited about Walgreens, which has shown how much it depends on ExpressScripts to get people in it stores.

Once a kingly retailer, Walgreens still the biggest pharmacy in the country. It’s also cocky as hell. In its last annual filing, Walgreens warned investors that terminating a PBM relationship would hurt sales, “at least in the short term.”

That implies sales would bounce back. But no matter what it tells itself, pharmacy benefit managers now have the upper hand. Wagreens gets a significant portion of sales from prescriptions filled by PBMs. During the breakup. ExpressScripts sent customers to CVS Caremark (CVS) to pick up prescriptions, as well as toothpaste and any other items they realized they needed while walking to the pharmacy counter. CVS has said it expects to keep 50% of the business it gained during the dispute.
