coupon book

Here is my coupon book. I've had it set up for a while now it only take a few minutes to put my cut out coupons in it. Yesterday i put several hundred coupons in it from my scavenger hunt. My sister and daugther in-law have smaller version of my book. The three of us trade coupons. My daugther in-law belongs to a moms group she lets the moms group have the coupons that the three of us don't use. My daugther in-law mom group sends all the coupons that have expired to army family's. They are able to use the expired coupons.
