Website may spark change in medical economics: "Plymouth-based Carol.com, which debuted this month, is the first attempt in the country to put together an online medical marketplace. Its creators want to do for health care what Travelocity did for airline tickets. In doing that, Carol's creators are riding the leading edge of a wave of change headed toward consumers just as questions about how to cure the nation's chronic health care crisis are resounding from the corner cafe to the presidential campaign trail. Some think putting more choices in consumers' hands will drive down spiraling health care costs. Others fear those choices may be too complex for the average person to make."
