University of Chicago graduate student Andrew Mason was in a rut. There's so much to do in Chicago, he explains, but I found myself going to the same movie theaters and restaurants.To help people like him try new places, Mason started a website that offered coupons to large groups. He reasoned that people would try something new if the price was low enough, and that businesses would offer low prices if they knew they could sell a large quantity. The result was Group on, a company that offers group coupons in deal of the day offerings for local or national businesses. Consumers love the concept, buying everything from restaurant certificates, to yoga lessons, to tickets to a museum exhibit. We think the Internet has the potential to change the way people discover and buy from local businesses, says Mason.
