I have many of my books spiral bound but it has been awhile since I've done a new one. It used to be $3.00 to $5.00 per book to have them done. Now I am told they charge about the same but there is an extra charge to have the spine cut off so the holes can be punched for the spiral piece. Check with any office supply store such as Office Max(that is where I have mine done). Hope this helps.
