Excellent book and Jack offers an excellent online course and community. His teachings has literally changed my life and helped me grow my car rental business from 15 to now 30+ cars using 0% interest credit cards! YTD I have gotten a total $176k of 0% funding on one LLC that was less than 2 years old without ever being asked for or having to provide any tax returns etc. Jack's stuff is real. I can't even imagine the cost of not taking his course. I would have still been struggling to grow and using my own limited amounts of money for everything. Oh an not to mention I've traveled in multiple business class flights using points and very little money out of my pocket to my home country of Trinidad & Tobago using what Jack taught me. Like I said I can't imagine the cost if I didn't give Jack's book and his course a try.
