DEERFIELD, Ill. — Though total same-store sales were down 8%, Walgreens Friday morning characterized a first quarter lifted by a steady influx of returning Express Scripts patients and driven by a steady stream of new Balance Rewards members. The Chicagotown retailer has signed 45 million Walgreens faithful since mid-September. "Today, we have the wind at our backs as we head into a new calendar year," Walgreens president and CEO Greg Wasson told analysts Friday morning.
