I use a binder, too, but definitely am not an extreme couponer

But we also don't buy a lot of the products that come in the coupon section (prepared foods, frozen meals, a lot of the cleaning supplies, etc.).
But a binder helps me stay organized and I can 'see' everything right away. I got tired going through all those coupons in my little accordian folder all the time. and then all of it falling on the floor when I goofed lol.
A simple photo album would work for you if you wanted something to be able to flip through. But my binder cost about $28 by the time I found a zippered one on sale and purchased the inserts and index tabs. Now I can just flip each page and see exactly what I have coupons for in whatever section I am in. That way, I can take advantage of any unadvertised specials.
