That’s the crux of it, I think. The seller has to be willing and capable. You’re praying that they’re excellent. The onus is on them completely. They have to source the box, package it, wait for the courier et cetera.... Insure it correctly...... it’s time, expense and effort..... exchange rates, language barriers (to a certain extent).....
Im the seller/vendor in this instance & there is an element of trepidation to it.
