Rates have definitely gone wild for us mere mortals.
Within the last few months I got a complete used 216 valvetrain (rockers, shafts, everything) from another stovebolter and shipping cost $25 USPS.
Few weeks later I bought a used leather motorcycle jacket that shipped for $27, also USPS. (both shipped from east of the Mississippi if I recall)
Best shipping these days is definitely finding the right online retailer who can provide better rates than regular people can find.
