Here is what I would use to store my coupons in an organized and easy way.
I was in desperate need of a larger coupon holder and I didn't want to have to buy a binder and business card holder inserts. I estimated that to do so would have cost me around $10-$15 which would have defeated the point of all my coupon clipping these past few weeks.
I went digging in an old drawer and found a picture holder from the 7th grade (yes, that would be over 15 years ago). Thank goodness I didn't throw it out! There were a few crummy pictures in it and I hadn't touched it for years. I took the pictures out and created paper tabs (I cut my tabs using my Cricut but you can just fold over rectangles of paper) and stapled them to the inside. I then sorted my coupons. The labels are for the sections of the store, baby, dairy, meat, cereals, toiletries, medicine etc. The photo book spaces are the perfect size to store irregular sized coupons too.
Simple as that! They are now organized, easy to view, and easy to find. Now I'm not flipping through my messy stacks of coupons trying to find what I am looking for. And it's a great way to reuse all those picture books you are not using.
