Please review my terms of sale. If you are not ordering from the United States, there is a $US1.50 additional postage expense that needs to be added to the price of the stamp. If you are ordering from the United States, there is only a $US0.66 added postage expense. Also, if you make additional purchases from my offerings, they can all go in one mailing at no extra shipping expense for the added purchases. I will send the purchase by US first class mail, since the relatively low value of the stamp does not warrant signature or tracking mail. Hence the buyer assumes risk of loss or non-delivery. I will keep a scan of my mailing to verify that the correct mailing address was used. If not satisfied, return the stamp to me at your own expense, and I will refund the cost, but not my postage to you. If the stamp is not as described, I will refund the cost and reimburse you for postage both ways.
By way of reference, I am an American Philatelic Society (APS) member (195176) and an American Stamp Dealers Association (ASDA) member. Thank you for looking, and I hope this is the perfect stamp to fill that gap in your collection.
