Although many distributors insist on using UPS and FedEx to ship overnight FFL holders are allowed to ship to each other through the US Postal Service which has lower rates. I think with the adult signature fee tacked on total cost is in the $22 range compared to around $30 for the others. Regular gun owners cannot ship via the USPS, just FFL to FFL. Something to keep in mind to save a few bucks for an extra day or two in shipment.
