What is the cheapest way to ship something internationally, and what kinds of things are cheap to ship internationally? It turns out that packages are expensive, and letters are too small.
I’m a chronic overcharger of shipping. I weigh the object, and then add two or three ounces for a mailer, and one or two pounds if it’s going in a box.
It’s a psychological weakness: I just don’t like to take a loss on shipping.
