I remember she tried to overhaul their drug cost model to be less opaque and supposedly cheaper for consumers. Doesn't seem like it ended up happening from my point of view. CVS is my PBM and keeps raising the cost for generics to the point where it's cheaper to buy them without using insurance from an online pharmacy.
But I wouldn't want the new jerk who replaced her to escape attention, seeing as he came from the PBM business and is likely the reason for my above complaint.
