First, I get all of the same inserts together and I separate all of the pages. Then I stack each of the like pages on top of each other.
Next, I staple each of the coupons.
Then, I cut them out and put them in my coupon box.
My coupon box is actually a photo box that I had. It came with category separators, and then I added envelopes for each subcategory. For example, I have a separator for Cleaners and the envelopes within that category consist of air, all-purpose, laundry, dishes, etc.
This makes it very easy to find and organize my coupons.
I would love to hear feedback on your organizing method.
