PBM/NO PBM, who cares? It makes no strategic difference when you have no idea of how to run a retail pharmacy business in the first place.

CVS: vote NO.
Both these sickly companies are drags on a prudent investor's financial health. Steer clear.

Losers like Duane Reade and Longs Drug, and countless other wastes of shareholders equity.
