Minute Clinic-Opening up at a CVS Pharmacy near you

http://www.minuteclinic.com/ I see this as a threat to our specialty with Nurse Practioner(NPs) and Physician Assistant (PAs) staffed walk-in clinics at the corner CVS pharmacy. I heard that Walmart is close to signing on with Minute Clinic so they can send their employees there for cost containment purposes. Should we boycott CVS pharmacies and inform our patients that we will no longer fill their prescriptions at all CVS locations? How should we respond? Not only is this down the street from my office but it also competes directly with our urgent care. This will impact our business!!!!
