Where can I read Vinland saga?

I’m not an anime guy, and I haven’t read any manga, but Vinland saga is truly a great series which I thoroughly enjoy. The problem is that it’ll be a very long time before s3, and more comes out. Therefore I am considering reading the manga, where should I read it, or should I buy the books maybe. I’m Norwegian, so some sites may not work. I looked at mangadex but I haven’t got a clue to how it works, and it’s community translated. Is the community translation as good as the official? That aside, Vinland Saga is peak, and it really gets to me. What should I do?
