Hi all. I've searched the archive for this list but have failed to find what I'm looking for. Where can I purchase 11 1/2" by 11" 19-Hole punched covers for books? I see that APH has them, but I'd prefer purchasing them in larger quantities than paying $2.50 for just a pair if possible. So far, I've only seen covers for regular sized documents. While I'm on this topic of binding, are there any combs bigger than 2 inches? Thanks for any help you can give me! -Alyssa
