I also use a binder with pages that hold baseball cards. Except my coupons are alphabetized by A-Z instead of catergories...bread..cereal. this works so much faster for me when I'm at a store and find a great unadvertised deal so i just flip to the letter that starts with name of the item.. bic soleil...charmin
My binder is as "big as my head" also so i put it in a canvas tote i got for free for signing up at Books a Million. My DH thought I was crazy for carrying it to K mart once but he changed his mind when he noticed i got shaving items for free that were on clearance.
