Extreme Couponing question...?

I have just started getting alot more serious about clipping and using coupons. Today at the grocery store, I bought $13.00 worth of deodorants,and hair care stuff. After my coupons, I only paid $6.00 for my stuff. So, because I am using so many coupons, I want to start using a big 3 ring binder. I have one of those already, but what can I use to "hold" my coupons IN the binder? I have ALOT of coupons, and keeping them all in an envelope is just NOT working, cause I have so many. Any suggestions from serious shoppers out there?
