A key step to keeping your coupon binder, folder or file system organized is cleaning out expired coupons on a regular basis. Set aside a time every week (or month) to go through your binder. Consider choosing the end of every week before you insert new clipped coupons, or the first day of every month. Rotating out unused coupons will create more space.

If you often forget to use coupons before they expire, try to keep about-to-expire coupons in a prominent location, such as a designated envelope or 2–3 extra baseball sleeves at the front of your binder, or keep a running list of coupons you have, organized by expiration dates.
