Looking for a deal? Google it! The search giant (and up-and-coming global empire) has quietly introduced the ability to search for printable coupons in Google Maps. As local search blogger Mike Blumenthal notes, apart from some coupon-related domain names spotted last month, Google’s work on the service has largely stayed below the radar. Nonetheless, its coupon search can be easily conjured up to find deals at Boston restaurants, specials at San Francisco dry cleaners, and yes, coupons for Honolulu businesses as well.
