Yes I might want to go to Loompanics.com or Paladin Press and order a book. Then I might get put on a list for ordering books on the subjects that they publish.
Try these places. I wager that a lot of people don't know that they exist.
Already familiar with them. In fact, some 10-15 years ago, I got a Loompanics catalog. I haven't checked them out recently, though.
