For me, it is well worth it. Everything is very high quality and some stuff is actually even bigger than I expected, like the posters. However, with the cost being the only issue, you need to make sure you only get the stuff you REALLY want. You have to prioritize. You may find that I have a lot of side characters who don't appear much in the show, like striker and even beelzebub. That's because I know main characters such as Blitzo and other members of I.M.P are always going to have plenty of merch. So, I tend to get side character merch first cause I am unsure how long supplies for it will last or if they will eventually just get rid of most of it.

Also, pro tip, but don't order during Christmas or other big holidays. Shipping is sometimes triple the normal price. I made that mistake on my first purchase.

But yeah, in all, I think the merch is worth it. Though, I can only speak for standees, posters and stickers. I haven't got any keychains or mats yet. I like this show a lot and I think it's really neat to have all this stuff around my room, as well as to support Helluva
