[no spoilers] Official merchandise?

Hello to everyone in this awesome subreddit i just found. I'm a little hesitant upon making this post as i'm not sure i'm violating any of your policies, if that's the case i'm very sorry.

I'm very interested in buying some merchandise from the show, but i'm struggling to find any place where the profits will go to the people it should! Does anyone here know if any official merchandise is on sale anywhere? I've found only fan-made content, and although good, I really wanted something that would support the creators since i never bought any of the dvd's from the episodes.

Many thanks and cheers to everyone
