In this economic slump, this book is guaranteed to save you money. From personal experience, I can tell you what a "natural high" it is to walk into a store with my shopping list, in complete control; knowing how many items I will purchase, for what price, and even stay with that planned total cost. I don't have to deal with coupons, refunds or matching prices, unless I want to. After my learning curve, I will recognize a true loss leader and be able to capitalize on the lowest price out there.
This is a great reference book that every household should have.
