How I organize my coupons

I have tried a few different methods, but here is how I currently organize my coupons. First of all, if I have several of the same inserts I usually only clip one. I use an empty baby wipes container to store my coupons. It's the perfect size to fit several letter size envelopes. I stapled an index card to each envelope and wrote the name of the coupon category on each card. Voila! An easy filing system that was practically free to make.
