The easiest method to getting the best deals is to have a library of inserts saved up. That way, if an item goes on sale four weeks after the insert is delivered, you’ll still have the coupons (and you only clip the ones you actually need!).

Accordion Coupon File Method
Not as pretty as the binder method, but very time efficient! Just make sure you date your inserts before filing them.
Organizing Other Coupons
You’ll always end up with cut coupons you didn’t use or coupons you found in the store. Organize these in whatever fashion fits your life best. Small accordion files, envelopes, or a binder are all good options. Most of the time, we know about these coupons, too, and will reference them in the shopping list for your convenience.
