Unoppresive Non-Imperialist Bargain Books is a staple of Carmine Street. It has been there for 23 years and, as the title indicates, sells books that are at a bargain. It appeals to niche markets such as Bob Dylan fans from all over the world, as well as fans of some obscure authors. It shares a marquee with a store called Carmine Street Comics. There is a lot more information, but it’s best if you just watch the video.
