I read on the internet the other day that if you mail books, magazines, or cd's, then you can mail them media mail which is a whole lot cheaper. I think their example was mailing a 10lb box of book from NYC to San Diego would cost $16, but shipped media mail would only cost about $5. But you can not piggback anything else with it. Have not had the chance to try this yet, has anyone? With all the books and magazines that get sold on here, thought we could give this a try.
