Jamie Sheehan of Glen Mills, Pa., helps run a Facebook page called "Expired Coupons for Overseas Military."
"We take expired coupons and we forward them to military bases where the tamilies can use them," Sheehan explains. "They can use them for six months after they expire."
So, even if a coupon's no good anymore here in the States, it can be a real money-saver for military families.
Sheehan explains the respons has been gratifying. "They don't get newspapers over there with coupons in them and a lot of time, going off the base is very difficult because of language barriers. So the fact that they're able to use them... they're very grateful."
Jamie collects expired coupons from friends and family, and in a box at her local library. She then clips them (to maximize how many she can fit in a box or envelope) and ships them, paying the postage herself.
But the page encourages couponers to adopt a family or pick a base and send them directly. And it's not as expensive as you might think.
"About 50 coupons will fit in an envelope. for just $.44," Sheehan says. "If you're shipping to a military base, it's considered domestic mail, (so there's) no extra cost."
