HEY!!! I've GOT IT!!!

Instead of sendin' all packages to the address of the recipient, send 'em to the nearest Tim Horton's up there, and THEN just let good ol' Tim take care of all customs charges and such!!!
Uh huh! And THEN you guys up there can just pick up your packages of spares and accessories the next time ya feel like a doughnut or two!
(...oh, and a cup o' coffee of course!!!...yeah, yeah, I know...I'm a "whole lot o' help"...again)
