Shipping costs are listed in the Shipping and Payment section. Worldwide shipping available.

MULTIPLE ITEM SHIPPING DISCOUNT:  In most cases more than one item will ship for less than the cost of the individual shipping prices added together.  Ebay will only add up all the individual shipping costs unless you put multiple items in a cart and request total from seller, before paying. You buy an item but instead of paying you add to a cart, then buy another and do the same. When there is more than one item in your cart Ebay should allow you to request a total. At that point I am able to see your order and I can send an invoice with discounted shipping. Keep in mind I don't work 24 hours a day so it might take a bit of time for me to respond. 

Thank you for looking at my store.  I appreciate your business.
