Duck Commander hosts Uncle Si Robertson November 11, 10 a.m. to 2 p.m. CST, at its West Monroe, Louisiana store for Veterans Day. First 100 in-store buyers over $100 get a meet and greet, photo and signed cup, while 10 percent of proceeds from every Uncle Si Day order go to LifeCampUSA, which Uncle Si selected for young men and women who lost a father due to service in the U.S. military, law enforcement or as a first responder. Online spend over $75 that day yields a free Uncle Si cup, plus 100 cups he signed for qualifying orders.
