Best hole in the wall thrift/antique stores?

What are the best hidden treasure secondhand stores? I think I know most of the main ones, but I'm curious if I'm missing any. Im talking musty, dusty, filled to the brim, unsure if they take card,cursed-amulet-selling type stores. Like J&J Junk, Jennie's Corner, goodwill outlet type vibe. I wanna get grimey and obtain collectibles for very small amounts of money 💪
