If you live in Michigan you have an opportunity to kill two birds with one stone. That's because Mario's Pizza, located in Union Pier. is offering a $30 "pizza and plow" promotion. Restaurant co-owner Tony Gloriosos explains he started the promotion last month after business was slow, so he decided to offer his plowing services along with the pizza for a special price. He says the price could change, depending on how difficult it is to remove the snow, but he plans to keep it up all winter long
