I should not be saying this as my son is a UPS driver. Anyway, all my gun shipments go by USPS; either priority, registered of express mail. Priority gets there in 3-4 days, registered takes a bit longer and you need to wrap the package in a "kraft" type paper. It is then stamped along all the seams with the PO stamp and is signed for by anyone who handles it. There is definitely a paper trail that follows it. Registered is fast, shipped one from MN to AK and it got there overnight. All are the same price. If you go to the USPS website and register, you can determine shipping and insurance costs there. I then go to "click 'n ship" and fill out the form online, pay by credit card, print the label, tape it with clear tape to the package and go to the PO and drop it off on the counter. No need to talk to anyone. I just place it on the counter and leave. The thing about the overcharge earlier is the weight was probably why you got charged so much. The package I shipped to AK was 18lbs and insured for $7500, cost was $104. I probably ship over ten packages a month that way and never had a problem. UPS insurance is a sham, from what I am told they will no longer take insurance for more than $100. The rest is up to you through an independent insurance company.
