What to do with expired coupons

This is just a quick post, but I just sorted out a bunch of coupons that expired 2/12-2/15, and I knew I had read somewhere about sending them to our troops. Here is a website, by a woman named Toni, who started an awesome way for us to send them our coupons (they take them overseas for up to 6 months expired). Please link to her and get involved if you are so led!
