There was a post on another forum where one of the members told another member to send 15 or so co2 cartridges through the post or a courier as no one checks and because other companies post them to you by mail or a courier then its legal for a private seller to do so and he said the going to Belfast thing was a myth despite two others saying their airguns were in Belfast at that present time .

People forget that the public can't post thing like companies can due to trade accounts.
