Walgreens has signed an exclusive deal with Foursquare, which it claims makes it the first national retailer to offer scannable point-of-sale coupons. Customers who check-in at any Walgreens store nationwide using Foursquare on their iPhone, Android or BlackBerry will immediately get a  coupon, with no texting, reply or other steps required. The program is kicking off with 50% off all varieties of AriZona Iced Tea cans. Walgreens, which launched its own mobile app during the holidays, say it has already been downloaded 500,000 times.
