There are multiple ways to organize your coupons....filing by insert, cutting and filing, or binder/baseball card holder.
I personally use the baseball binder method to organize all of my coupons. It takes a lot of discipline and some time to do this. However, I'm able to flip to what I need in a matter of seconds in the store where I need to be quick with 3 kiddos.
I have it sectioned out into categories that work for me such as dairy, dry goods, baby, pet, etc
I bought this cover that holds everything I need in one place. (Thanks Misty (: )
It folds up into a handy tote that I can throw over my shoulder :)
