For multiple items, load them in your cart and when you are finished, commit to purchase the items then ask for a total.  Shipping charges are $2.00 ($3.00 for outside the USA) for the first item and $.25 for each additional item.  I will adjust the shipping charges on your invoice.  If you overpay on shipping, I will refund you any overage.  Ebay is supposed to do it but sometimes it does not calculate correctly.  Thanks for your business.  Bob
