it doesnt cost 22,50 to ship in canada ,you could check in my auctions i won many tablets from the us and the most the people had pay is 20$,and it's not the same pound for sure ,anyway it,s up to the seller to decide what she wanna do.
It's fleet post office . It's a service through the USPS that ships to all us military bases world wide . You attach a small customs form and pay usually less than domestic rates because you are actually mailing to a miltary base in the us and then the miltary handles the majority of the freight .
