My guess is that purchasing a brand new pair from a local Norweigan dealer like
fue.no - Dykkerutstyr & dykkerkurs - Nettbutikk & butikk i Oslo - Hjem would be the preferred way rather than paying extra cash for shipping costs for items outside of Norway. Taking in mind that you would have to pay import tax anyhow.
Or you could even order them from let say
SeaPro Divers Webshop for 445Sek-20% Tax+25% Norweigan Tax.
