Pay postage only on the first item you buy (with the highest estimate for posage). All additional stamp sets or single issues mail at no charge for postage. Because of problems with foreign mailings to some countries, Items selling for more than $50 will only mail for the cost listed above of priority mail, or registered mail to select country. Please take this into consideration when bidding. This will not apply to repeat customers who have a good record of providing feedback upon delivery.
