If it’s not a well known site, it’s probably just a malicious site. They sometimes clone or mimic content that is searched for in order to get your attention when you google. I would avoid this unless someone personally recommends it to you or they actually offer a physical product.
I’ve searched (and once in a while found) some pretty rare stuff on the web. It’s cool, but be careful. You’re trying to find something rare while a lot of places on the web are just trying to to get their hooks into you.
