eBay

The most common problem I encounter is a buyer wanting to buy a couple items but need an invoice before paying that shows my discounts for combined shipping. Buyers often say they don't get this option to put items in cart but have to pay for each it...

How do I now go about giving a refund for combined shipping overpayment. A buyer purchased two items and was charged the full shipping on both items but I offer combined shipping for the same cost which they did not receive at time of purchase.
