I just sent a package, a FX Whisper T-12, from Washington State to Illinois insured for $500. The cost was $59.19 and the USPS was the carrier. I noticed on the box that was sent to me from AOA they shipped it UPS and it cost them $38. I didn't bother to go compare what it would have cost UPS as I am rural and would have to drive about an hour to an official UPS store. I am sure I would not get the same rate as AOA, however. I posted this as a question earlier and now have direct experience to share with the forum.
