I found what works for me at Walmart for about $3. It is a plastic organizer, 4.5″ x 7″, and fits in a compartment of my purse, so I have it with me at all times. The organizer has an elastic loop that fits around a plastic button for closure. It comes in several colors; mine is a light lilac. Inside are 12 plastic dividers with tabs on each for letters of the alphabet, 1-3 letters (provided) for each tab, e.g., A, B, CD, EF, GHI, etc. I group my coupons alphabetically by what they’re for such as “T” for toothpaste and tea. Then I place them in expiration-date order (earliest on top) within their group and secure each group with a paper clip. At the end of a month, I toss any coupons I haven’t used for that month, then quickly go through my alphabetized and chronological groups and take out all coupons that expire during the next month. Still in groups, I place these at the very front of the organizer for easy access that month. Depending on the number of coupons, I may stack them in one group, in expiration date order, or I may leave them in their mini-groups, still in expiration-date order. Obviously, this system can be adapted to others’ needs or imagination.
