We're happy to combine shipping. For USA ORDERS, We ask that you keep you're unpaid auctions no more than 7 days apart and less than 20 days old. Please let us know when bidding on other auctions so that we can make a note of it. Once all auctions finish, let us know and we'll send an invoice for the combined orders. For INTERNATIONAL orders, we'll have to make a special listing for you which will greatly reduce your shipping costs so please do not pay until you message us. We're extremely easy to work with as long as you communicate with us. :)
