Cigna

In yet another massive attempt to remake the health system, or at least change your declining fortunes, Cigna is buying PBM Express Scripts for $67 billion.  This makes Cigna more like UnitedHealth and Aetna, if the CVS merger goes thru, in having a substantial stake in the pharmaceutical game, and it will whack UnitedHealth's OptumRx unit, as it currently works for Cigna.
