[Addicted]

I have searched all over the web but can't find what I am looking for anywhere and with 2 kids, I don't really have time to search stores. Here's my dilemma: I have a 3 ring zippered binder (it used to be a planner ) and it's not one of the big ones, I think it holds around 8.5 X 5.5 pages. I want to use this for a coupon binder because I want to Go Green and reuse stuff. right now I'm using one of the accordian style ones and it is NOT working out for me. My problem is I can't figure out where to get the baseball card/photo sheets to fit it for a decent (cheap) price. I had a friend suggest comic book protectors ? but I'm not sure that would work out since I don't know if I could separate them into slots correctly. Does anyone have any suggestions or an idea of where to find something that size that will work? Thank you all for your great ideas!
