I hate to see coupons go to waste. 
Me, too. When Joann's has their coupon sales, it's great fun to try to find someone who needs some that I'm not using and give them to them. Yesterday, I was at Target, and had coupons from the Sunday paper. There was a lady looking for a Barbie "in a red dress" that her granddaughter wants. Apparently, that's the holiday Barbie and it's $40, which was out of her budget. One of my coupons was for 25% off a Barbie item. Grandma was delighted to be able to get the doll GD wants, and still stay in the budget she had set. It was great to see the look on her face!
