Amazon does it different in Japan. They put items on a stiff piece of cardboard the same size as the box they will eventually put it in. Then shrink wrap the items and the cardboard. Then they glue / rubber cement the bottom of the cardboard to the shipping box. It seems like it uses less material but the boxes are designed to be torn open like a FedEx envelope which means they are not reusable which seems wastful
