Spotted these cute file folders on clearance for just $1 near the school supplies at Walmart. They had a few different designs to choose from.
I like using a file folder like this to organize my coupon inserts. I file them in order of the week received and move them back a spot when a new insert comes out. This makes for easy access to the inserts when you need to find a specific coupon and know the date of the insert! And for a buck, this is a great deal!
