USPS changed the shipping rates again on January 04, 2010. The changes are mainly small increases, which we will note in this guide. We still continue to examine the ongoing buyer-seller dilemma. How can sellers charge fair shipping fees, and still make a profit? Is there an easy way for buyers to analyze a seller's shipping policy to determine whether shipping is too high?

First, let's become educated about USPS shipping. In 2007, USPS not only raised their rates, but also changed the method by which those rates are computed; placing their emphasis on the shape and size of packages, and machinability, rather than solely on weight. The theory is that costs can be contained by rewarding machinability; so the automated scanning and processing machines can be used to the fullest, and to reduce the need for human intervention. A small fee is charged for nonmachinable packages.
