honestly I just checked other GB threads and copied their rates, so I really cant explain why the way they are, as I've never shipped internationally. The thing is, 1 key, 5 keys, 10 keys, 20 keys can all fit in a bubble mailer and would ship for the same price. So if you order 3 keys, I understand that it seems steep. But if you order 4 of each, it wouldnt seem so bad.
