Check the listing for details. U. S.Stamp FDC-1311 - SIPEX - Art Master cachet-comb. shipping. Listed at 0.99 USD. SHIPPING AND POSTAGE: I will combine shipping, but because this is a buy it now offering, you can buy the items you want and then I will refund you a portion of the total cost for each additional item. Alternatively, you can buy what you want and wait for me to invoice you with combined shipping. PLEASE MESSAGE ME AND LET ME KNOW YOU WANT TO COMBINE PURCHASES. I also have other First Day Covers, plate blocks, mint sheets (U. S. postage and U. S. Christmas Seals) listed at "auction" and "buy it now" - I have two batches of auctions per week, one ending on Saturday and one ending on Wednesday. If you want to combine shipping with any of these, please let me know. Anything I mail with a total value of over $50, I mail USPS Ground Advantage, so you'll get a tracking number.
