It really depends where you ship them. I agre that USPS is the cheapest, up to a certain point. I've shipped many many skis this winter, and Ive found shipping from Michigan to the east or rockies is fairly cheap. Shipping all the way out tocertain parts of California though is very expensive, running over $30 not including insurance. Also, UPS has a larger upper limit on boxes before they are classified as "oversize" than USPS. Once a box is oversize in USPS, you can expect to pay around 3 times as much! However, the USPS Priority Mail is a great deal, and one that I most often use. Check it out.
