Wanderful Media, a company that partners with major American newspaper companies to bring online their Sunday “circulars” — or their flyers, deals and coupons the companies insert inside of their newspapers — continues to ravage up money. The Los Gatos, California start-ups said Monday it has raised $14.5 million in additional funding, bringing its total to more than $50 million. This is the fourth round of backing in less than two years.
