Trouble is, if you've got a disorganized nature, the disciplines of the frugal life can seem daunting. First publicized by Amy Dacyczyn, author of the Tightwad Gazette newsletter and book series, a price book is a tool for tracking prices, sales and buying opportunities. It's a simple but powerful tool to save time, money and supermarket stress.
Form is unimportant.
Low-tech tightwads use a small binder or spiral notebook to track price book information. Planner aficionados devote a tabbed section to price book pages. Whatever the form, the heart of the price book is the product page. Each page tracks price information for a single staple product. Down the page, you'll list the date, store, brand, size and price, and unit price for that product.
