Anyhoo, I found that I'd stick them in my wallet and then forget about them or have to ruffle through them at the store trying to see which ones I had. Then as I was cleaning out my daughter's closet I found a little album that I had gotten when I was pregnant with her.
Now it is my coupon book! I love it! It stays in my car in all its bright pink glory just waiting to save me 50 cents each shopping trip. Score.
I'm sure that this is not a new concept by any means to the majority of people in the world, but it's new to me and it's a lovely little discovery. :)
