I would imagine the cost would be contingent upon the size, weight, declared value and associated insurance--all determined by the specific "package" you would purchase--as well as the speed of the shipping method. These may seem as obvious however.....
To answer the original question, I just got some US to France shipping quotes for three different packages via global express. Here they are:MBPKG-A $195.25, MBPKG-B $166.75
and MBPKG-B-DOD $176.25. I assume that the price would be approximately the same for a shipment to the uk.
