A couple of years ago I was trying to get a decent price for shipping a frame to Norway and found a couple of great possibilities... although neither ended up working for me.
The best price I got was from the local post office... about $160. The local postmaster checked a "priority by weight" type parcel to come up with the $160 figure. As it turned out with my frame, the size was just a little too large and didn't come in under the restricted size. You might have the seller check with their local post office to see if the Amen frame weight and size would fit the "priority by weight" category. I think the Amen frame is smaller than the frame I was trying to ship. As I understand from recent news headlines, Shelby, NC is a relatively small place, so maybe the post office people there are as friendly and helpful as those here in Hoopeston, IL, population about 5,000.
The second best price was about $330 by FedEx. The normal price I found online was around $600, but when I called FedEx to check, I somehow ended up in a “Great Rates” department. In my discussion with the person there, I estimated that the the frame was about 52” x 24” x 13” and weighed about 45 pounds. I was told that because of the large size of the profile, the price would be based on 112 pounds… the “dimensional weight” of the package. After some further describing of the “package”, I was given a price of $330 and change for the slowest shipment… which was less than 2 weeks. Again, maybe the seller would be willing to call FedEx and hopefully get in contact with the "Great rates" department and come up with a decent price for shipping.
I did actually end up getting the frame shipped, but it was by a guy who worked at FedEx and got special rates. the fella who bought my frame had also previously bought one from that guy, and I ended up sending the frame to him in Kentucky, then he sent it on to Sweden.
