I understand that some shipping prices can get pretty expensive, most of the time if there is a couple sheets of canvas and shapes that are with the order it's better to handle those in boxes so the weight of the objects are over the 13oz regulation for a first class shipping method thus meaning the price goes into a package form and is known as standard mail. We get all of the rates from USPS.com and UPS.com once you enter in the correct information on where it is the package is going and we have weights on the products to get the best rate we can from both of the websites. I hope this helps :)
