Depending on what kinds of books you’re into: https://www.pmpress.org/ https://www.akpress.org/

It doesn’t answer your specific question and isn’t meant to be preachy, just want to say that I’m shocked more people don’t use public libraries for books they don’t want to keep forever. Check it out as often as you want, no need to keep it on a shelf, if you really love it, then buy it.
