Today at Staples I found a bunch of Mead Five Star zipper pouches for 3-ring binders in the clearance section for $0.50 each (reg. $4.99). I thought it might be nice for the inside of a coupon binder. On the front is a 4.5x7.5" pocket, a 2.5x7.5" pocket, and an elastic strap for a pen. On the back is a 10x7" pocket and another elastic strap. I got two of them. It's very thin. They had some others that were thicker so you could put bulkier things in the pockets.
