Seems like it is available here! I'd recommend this book, can't recommend "End Game" because I've never read it, and probably never will. I think most of that pickup artist stuff is seriously miss-guided.
This book is not really into Pick up, he wrote a book called "Seduction Community Sucks" Well the site u put is the official one, and i can't buy it i want free pdf
Why do you feel like you should have it for free? It isn't a free product. Sometimes you have to make an investment in yourself, and you'll take it more seriously by making an investment in it.
Feel your pain. Honestly, I spent some of my last money on books and what-not and they helped to change my life. Investment in yourself isn't a waste of money. Sometimes I'll pirate something for a little bit to test it, but almost always buy it officially if I like it, otherwise I don't use it. Supporting small content creators is the right thing to do. If you can't afford that investment, you can harness that as energy / drive to get into a more financially stable position in life.
