Expired Coupons

It feels like coupons expire almost as quickly as I clip them. When I originally started the couponing process, I would toss out (recycle) the old coupons- as I'm sure most people do.

I have found two alternatives to tossing out old coupons:

1) Walmart accepts coupons 3 weeks past their expiration date! Sweet!! =)

2) Mail them to "Coups for Troops" and from there, this organization will send expired coupons (up to 6 months expired) to troops overseas for them and their families to use. 
The mailing information is:
     Coups for Troops
     PO Box 147
