Well, no sooner do I post my comment above, that I check in on one of my old favorite mail-order places, Sinister Cinema, to find that they will probably be closing up shop in the early part of 2020.
They used to put ads in Filmfax Magazine back in the mid-/late 90s, and they're basically where I satisfied my movie jones. They were like ... say, Code Red for the VHS era, but not that banana suit wearing asshole and a LOT more film rights. I got my first exposure to one of my favorite films, "I Bury the Living" through them. I had this incredible "Drive-In Double Feature" tape with White Zombie and Devil Bat, which turned me on to Bela Lugosi's Poverty Row films. And, through them, I developed my love for the trailer comp.
They have a good copy of Sonny Chiba's "Golden Bat", and they're running their (maybe final) Summer Sale (12 movies for $98, postpaid). Check em out, I don't get shill bucks or anything; you might find some interesting stuff.
