I know with our pipes, for small individual orders within the U.S. we ship USPS Small Box Flat Rate Priority Mail which is $5.80. For us it's much easier than trying to calculate regional rates. With the Priority mail, you also get tracking and $50 insurance, so it's actually a pretty good deal. Unfortunately, shipping is costly. Even if you use the USPS Priority Mail boxes, packing materials (peanuts or bubble-wrap) are an additional cost of doing business and to help insure that the customer's pipes have a fighting chance at arriving to him safe and sound. No slight to the postal service, but as my own post mistress commented, if you bother to write "fragile" on the box, then those are the ones that they will pile 50 lb. boxes on top of when they load them in the trucks or on the planes!
