If you're looking to save some money or become more frugal this book is a good start. It is fairly short and easy to follow. I really liked how much emphasis the authors placed on the dangers of being too consumed with couponing. After all, stockpiling can easily become hoarding. Couponing, thus, should only be used strategically and to the degree that coupons match our interest.
This book is not only for the extreme coupon people, but for all sort of couponers. I, for instance, do not want to commit too much time and effort to couponing, but I appreciated all the insights shared by the authors, and would definitely be using some of the suggestions given in the book.
If you're looking for a get-rich-quick kind of book, then this is not for you, for no one would get rich through couponing. But if you want to learn new ways about being frugal, give it a shot.
