Target Corp’s (TGT.N) sale of its in-store pharmacies to CVS Health Corp (CVS.N) may encourage large supermarket chains with struggling pharmacies to look for professional drug store partners of their own. More than 1,660 Target pharmacies will become CVS units in the $1.9 billion deal, the first time a drugstore chain has expanded its pharmacy business within a third party retail store, pharmacy consultants and analysts said. Drug stores in recent years have focused on opening new stores, an effort which has slowed recently.
