I raised this issue in the Target thread and it looks like it may be coming true: "Wal-Mart Stores Inc said on Tuesday that lower margins in its pharmacy business had emerged as a drag on profits, as it gets paid less by drug plan managers and as fewer customers pay in cash, since Obamacare has increased the ranks of insured Americans. The company warned that the margin squeeze would continue for at least the remainder of the year, although a spokesman told Reuters the pharmacy business is profitable and that Wal-Mart has no plans to sell it or find a partner to share the risk. The disclosure comes as retailers weigh the merit of running drugstores on their own. In June, Wal-Mart rival Target Corp agreed to sell its loss-making pharmacy division to CVS Health Corp in a deal that will see CVS operate the pharmacies in 1,600 Target stores." http://finance.yahoo.com/news/wal-marts-drug-problem-pharmacy-010156307.html?.tsrc=applewf I am sure your grocery chains are going thru the same problem. Expect more consolidation in the pharmacy business.
