U.S. Postal Regulations do not permit this magazine to be shipped by media mail as it contains advertisements. The only options available for shipping is either Standard Mail or Priority Mail. Since this magazine weighs over the Standard Mail weight limit, Priority Mail is the only option available.
What qualifies as Media Mail is books, music and movies that contain only incidental advertising. That means no magazines, no newspapers, no comic books, and no video games. It also means things you wouldn’t ordinarily find in a library.
