Military families stationed overseas can use manufacturers’ coupons up to 6 months past their expiration date. My mom and I gather, clip and sort coupons to send out to the two families we have adopted. In addition to coupons found in inserts, internet printables and the Catalina coupons received at checkout can also be sent, as long as they are manufacturers’ coupons and have a remittance address printed on the coupon. Store specific coupons cannot be used.
If you are interested in adopting a family, you can contact Expired Coupons for Overseas Military (ECOM) to be matched up. They ask that you send out coupons every 4 to 6 weeks. Also note, mailing packages to military bases costs the same as mailing letters or packages within the US.
