Linux Journal is indeed based out of the U.S. so for those outside of the U.S. wishing to participate in this promotion, please check in to International Reply Coupons. They're supposively (so our local post office tells us) available for nearly all country members of the United Nations. IRCs are available for purchase at your local postal office. You purchase a coupon locally and enclose it in an envelope to your foreign correspondent. The party on the receiving end (Linux Journal in this case) redeems it for airmail postage at their local postal office. LJ will gladly accept these coupons. See http://en.wikipedia.org/wiki/International_Reply_Coupon for further info.
