Watch the video review of Puzzle Book Mastery by Dawud Islam of the Elite Tigers Group HERE. We love ‘leftfield’ sales ideas at the Tigers and this release definitely falls into that category. Ken Bluttman has created an excellent product that can create puzzle books in seconds that you can then sell on amazon in this evergreen niche. The beta testing results with this product were very favourable and it is a great way of escaping from the regular MMO niche. Check out my custom bonuses where I give you 5 great products showing you 5 more ways to diversify with other leftfield methods. Elite Tigers Group rating 4****/5.
