I have been having fun with it for a couple of years now. It isn't something that controls my like (think TLC's Extreme Couponing) but is a definite presence. There will be a month or two that I won't really find any deals, or really even look for them, but then I will have a month or two of fantastic deals!
I am still trying to come up with the "perfect" system for me. I have a large binder and a small organizer that fits in my purse. The binder is large enough to fit all the store ads and uncut coupons in the front pouch and then I put the cut coupons in baseball card sleeves in the main section. The tough aspect of this system is I have to cut the coupons pretty quickly and put them in the binder--which can be difficult with Catherine hanging onto me (and trying her best to eat the coupons). I put special coupons (free items and high value) and coupons that I know I will use in the small organizer.
I have so much to say on this topic, but I need to go...I have to run to the store and use coupons for two free gallons of milk that expire today!
