How I got $12k in book preorders in 1 month (yongfook.com)

There is an intro chapter and lots of content in the links referenced in the article, not to mention the slide (posted here and elsewhere).

You will be able to buy it once it arrives in April (you can add your email to the list for updates).

Ivan > the crowdfunding campaign went on for a month and naturally preorders have to stop after the campaign finishes... otherwise it kind of defeats the point of the campaign :)

The book will launch publicly in April. You can sign up to be notified at http://growthhackinghandbook.com
