“Fearing bad news as her son suffered with a cough, aches and a sore throat, Donna Bultez found help in the most common of places — her neighborhood grocery store. Just feet from the beeping cash registers, a few steps behind the frosted-glass door, Bultez was relieved to find that her son Trevor Belmont wasn’t suffering from strep throat. That she saved money by avoiding a trip to the emergency room was good news, too. More and more stores — from small-scale chains like Bultez’ local Hy-Vee to megamarkets like Wal-Mart and Target — have started trial runs with in-store medical clinics.”
