This booklet by Margaret Carter looks like it was written in the 1980's. The techniques recommended for making money require substantial risk of capital (at least $100-$1000) which directly contradicts the claim that no start up capital is required to start this business. Carter tries to get around this by saying that you can use other people's money in various ways. This is nonsense. If you don't already have the little bit of capital required to start this business you have no business venturing into it with other people's money. Also, the claim that Carter made $400 in the first 48 hours of starting her venture seems physically impossible using the methods she is suggesting. (Putting ads in offline print publications such as newspapers and magazines requires more than 48 hours plus you have to factor in the time it takes for the mail to arrive in response to your mail order ad in the newspaper.) I have seen a much better program for producing how to books sold as e-books on the Internet for $7. The people advertising that program even are so good as to tell you that is what they are selling you in their advertisement. Carter's book is woefully out of date and has no tips at all for how to market on the Internet. If you must purchase this book, at least look for it on Amazon under the title "The Easy Way To Big Earnings". Amazon has a few used copies available starting at a ridiculous $0.39, not $56 like Carter wants you to pay.
And a final note, I don't recall giving these people my phone number, but soon after I ordered the book I got a call from someone trying to sell me a coaching course based on Margaret Carter's work. I'm not entirely sure if that was related to the book purchase, but don't fall for that one either. These coaches will take you for thousands of dollars all the while claiming that you are using other people's money.
