Another way to find this information is to do a simple Google search. For example, one could place the following phrase into Google Search:  “(product name) + affiliate program”. (Replace “product name” with the name of the product you are promoting.) There is an interesting chrome addon called Affilitizer is available which makes this process easy.
I think the author means well and I think his story of going from dead broke to millionaire in 5 years is awesome. As he mentions, he did that with some sacrifices, including personal relationships. I wish he would have spend more time digging into this and its importance, as I feel like many people struggle with this. I think it's a great book for him to tell his story and what worked for him, but I think he should leave the financial advice to those that are much more familiar with how this stuff works. If you're looking for a similar book, but much better, I would recommend Set for Life by Scott Trench. For those interested in real estate, the section in this book on real estate is generally weak in my opinion. I agree with the author's position on putting less than 20% down in certain situations - his examples of why on this are right on. In general, though, I would suggest checking out BiggerPockets for in-depth real estate investing info.
In 2006, the most active sectors for affiliate marketing were the adult gambling, retail industries and file-sharing services.[21]:149–150 The three sectors expected to experience the greatest growth are the mobile phone, finance, and travel sectors.[21] Soon after these sectors came the entertainment (particularly gaming) and Internet-related services (particularly broadband) sectors. Also several of the affiliate solution providers expect to see increased interest from business-to-business marketers and advertisers in using affiliate marketing as part of their mix.[21]:149–150
Since you’re not taking on debt, you’ll also need a savings plan for big purchases that aren’t emergencies. Let’s take summer vacation for example. It’s simple! Create a line item in your monthly budget and divide the total amount by the months you have to save. You’re not living in debt anymore, and that means you can enjoy your vacation instead of having a credit card bill follow you home.
You might call it the time-money paradox. Most Americans trade the majority of their available time for a paycheck, and then spend the majority of each paycheck on depreciating material possessions. As the spending snowballs, many individuals desire a larger paycheck, which requires even longer hours and more responsibilities at work, leaving even less time to enjoy the income or possessions. It’s a vicious cycle that often continues in perpetuity until retirement or death.
Wealth has been defined as a collection of things limited in supply, transferable, and useful in satisfying human desires.[9] Scarcity is a fundamental factor for wealth. When a desirable or valuable commodity (transferable good or skill) is abundantly available to everyone, the owner of the commodity will possess no potential for wealth. When a valuable or desirable commodity is in scarce supply, the owner of the commodity will possess great potential for wealth.
In April 2008 the State of New York inserted an item in the state budget asserting sales tax jurisdiction over sales to residents of New York, based on the existence of affiliate links from New York–based websites to Amazon.[45] The state asserts that even one such affiliate constitutes Amazon having a business presence in the state, and is sufficient to allow New York to tax all Amazon sales to state residents. Amazon challenged the amendment and lost at the trial level in January 2009. The case is currently making its way through the New York appeals courts.
In the last 10 years, ShoutMeLoud has inspired millions of lives around the globe to help them earn passive income via affiliate marketing.  It would not have been possible if I had not quite my call-center job to pursue my passion. When I think about this, I find it amazing as for how my life unfolded when I took the courage of starting something of my own.
Affiliate marketing has grown quickly since its inception. The e-commerce website, viewed as a marketing toy in the early days of the Internet, became an integrated part of the overall business plan and in some cases grew to a bigger business than the existing offline business. According to one report, the total sales amount generated through affiliate networks in 2006 was £2.16 billion in the United Kingdom alone. The estimates were £1.35 billion in sales in 2005.[19] MarketingSherpa's research team estimated that, in 2006, affiliates worldwide earned US$6.5 billion in bounty and commissions from a variety of sources in retail, personal finance, gaming and gambling, travel, telecom, education, publishing, and forms of lead generation other than contextual advertising programs.[20]

The concept of affiliate marketing on the Internet was conceived of, put into practice and patented by William J. Tobin, the founder of PC Flowers & Gifts. Launched on the Prodigy Network in 1989, PC Flowers & Gifts remained on the service until 1996. By 1993, PC Flowers & Gifts generated sales in excess of $6 million per year on the Prodigy service. In 1998, PC Flowers and Gifts developed the business model of paying a commission on sales to the Prodigy Network.[8][9]
