The CVS-Walgreens war could leave you the victim

Walgreens and CVS pharmacies are engaged in a war, and the loser could be you. If your pharmacy benefit is managed by CVS Caremark Corp. you could soon lose the option of having your prescriptions filled at a Walgreens pharmacy.

Background: CVS is not just a chain of pharmacies. One of its businesses is CVS Caremark Corp. which handles the prescription-filling part of your employer's health care program. It offers you a huge selection of pharmacies you can use, as well as a mail-order option. Because health plans want to offer as wide a selection of outlets as possible, CVS Caremark has included the 7,500 Walgreen stores in its network.
