Wine.com decided to leave Michigan to protest a new shipping law. Indeed the state passed a law banning retailers from shipping wines to consumers, and specifically the use of third-party delivery services such as FedEx and UPS. Since wine.com just launched aspecial delivery service, it is againts it best interests to keep working in Michigan.
Of course, consumers are upset but seem to be used to the decisions of their legislators. Some attorneys on the other hand claim that the new law is open to challenge, because the Supreme Court has ruled that states should not make it economically impossible for a company to do business. There might be hope for Michigan wine consumers!
