$19.97. You’re probably wondering how much this e-book costs, so I’ll come out and get the big mystery out of the way. If you’re of the opinion that information should be free, check the price tag on that college diploma filed away somewhere (you have HOW MUCH in student loans?), or on any paper book. Considering the book offers to save you a potential of $1,000 by doing stuff you’re already planning on doing, it doesn’t take much to save the cost of the book and then some.
