These are unopened. This item is sold as-is, no refunds. I combine shipping at full listed shipping for the first (highest shipping cost) item, and 1/2 for the second item and 1/4 for each additional item. You must contact me to send you an invoice with the combined shipping. It is not automatically calculated. To request an invoice, add the items you want to cart and then go to the cart and request the total. Be sure to check out our other listings on eBay.
