I use a 4 inch three ring binder. I use the page protectors for currency which are available at amazon.com. It provides 3 pockets horizontal pockets that are the width of the page. Coupons all fit no matter the shape/size and are easy to retrieve. I cut the coupons and file them by categories. Then, every week, I go to couponmom.com and save about $70/week and sometimes more. It is great.
