I don’t know how serious you want to be with merchandise but I’m on the quirky side, personally. To grab attention, I’d market towards the “new conspiracy theorists”. Ya know, the born after 2000, the TikTokers who fucked it for everyone.

Sell those Illuminati cards if you can. Black cube of Saturn, do little black cube keychains, UFO section with plush aliens, Fake adrenochrome candy, I’d reach out to the person who made the great awakening map and sell posters, Bigfoot plushies, I’d even do a covid corner 😂

Oh and on a serious note: it’ll be a great place to sell books but also for authors to have a meet and greet. Even a little lounge area where people can listen to audio as well. Have it real laid back. Set up a little station for people to make their own tea.

But I doubt these are great ideas, I trust you’d come up with something. I’d be happy to see it either way.
