Our pill-popping nation is paying off handsomely for Walgreen ( WAG). The drugstore posted a 3.4% jump in June same-store sales helped by pharmacy sales. Pharmacy sales grew 5.8% during the month, despite the negative impact of new generic drugs. But front-end same sales, which include discretionary items like cosmetics, fell .9%. The company also saw weakness in season items. According to Thestreet.com's most recent store checks, Walgreen's limited selection of these items didn't help. Total Walgreen sales increased 9% to $5.24 billion.
