Horror and movie collectibles stores

How many in your life have you visited and can you compare? I read that the best horror store ever is Halloween Town in California. Has anyone ever been there?

Here in my country, Slovakia, there is a couple of such stores and they have gained a big popularity with some of them having things that the other stores don't. They nicely add each other and the owners even met once a year on a small comics saloon event that takes place every year in the city. It's not the kind of competition you would think these stores would held against each other.

I have visited similar stores in Paris, Spain and Italy too. I thought the ones in Spain and Italy weren't as impressive as the ones here, but then again it has only been small coastal towns that these stores have been located in. I have also been to some in Wien, Austria, which is not too far from where I live and those were probably the best I have seen so far. One of them even had a Michael Myers mask on display, which I think is really a rarity in this part of the world.

Ironically, when I was in the U.S., I didn't visit any horror/movie collectibles stores. I'm eager the read about your experiences!
