The first step is to collect all the coupons you can get your hands on. There are websites that offer printable coupons, coupons that come in the mail, and of course the Sunday newspaper offers hundreds. Next, you need to organize these coupons somehow. I use clear plastic sheets to hold my coupons and store them in a binder. I then use my Rite-On tabs to create different categories like "Albertson's" or "Pizza" so I can easily find them before I go to the store. Another way to organize them would be to use Month Tabs to organize the coupons by their expiration date.
The key is to stay organized and save money...or at least spend money on fun things, not food and gas!
