Combined shipping should work for these sales. You have a few days after a buy to ask for an order total/invoice. This allows me to send you and invoice for multiple items. This usually means shipping for one item is the same as multiple because the weight and dimension limits are high for the eBay USPS shipping. Happy shopping and welcome. If anything in that experience does not work the way eBay says it should, message me.
