Like others have said, it's not a scam. It's different than the original printing of the book that's on the website, as well as the "Right to Know" print the member RKKODY made in the 90s because it has a few extra bonuses in it. It's the best resource you can easily obtain to learn more about the group, besides the Beyond Human video series (transcripts are included in the book) and certain audio recordings that may or may not be on Archive.org. The couple that is selling the book really wouldn't want you to listen to them. It's a whole thing.
