Federal law does NOT mandate that a non-FFL holder has to ship from one FFL holder to another. That decision is up to the FFL holder. That choice is most often a method of gouging the buyer.
sigh.... here's the relevant info :
(B3) May an unlicensed person obtain a firearm from an out-of-State source if the person arranges to obtain the firearm through a licensed dealer in the purchaserís own State?
A person not licensed under the GCA and not prohibited from acquiring firearms may purchase a firearm from an out-of-State source and obtain the firearm if an arrangement is made with a licensed dealer in the purchaser's State of residence for the purchaser to obtain the firearm from the dealer.
[18 U.S.C. 922(a)(3) and 922(b)(3)]
and another reference from the same ATF web site:
(B8) May a nonlicensee ship a firearm by common or contract carrier?
A nonlicensee may ship a firearm by a common or contract carrier to a resident of his or her own State or to a licensee in any State. A common or contract carrier must be used to ship a handgun. In addition, Federal law requires that the carrier be notified that the shipment contains a firearm and prohibits common or contract carriers from requiring or causing any label to be placed on any package indicating that it contains a firearm.
[18 U.S.C. 922(a)(2)(A), 922(a) (3), 922(a)(5) and 922(e), 27 CFR 478.31 and 478.30]
and here's the link to the ATF site that I got the info from:
If you'd like to give me an idea of what part of the state you're in, I may be able to steer you to a reasonable dealer.
