Thanks for contributing to our forum. In order for your eBay listings to show that international shipping is available, you should need to indicate which international destinations you are willing to ship to and specify which shipping services are available for those destinations when creating your listings through Auctiva.
Once you have clicked the "Maximize" option next to the Shipping Tools section on the Auctiva listing creation page, you will want to make sure to do the following 3 things to make sure international shipping will be offered:
1) Check the boxes next to the international destinations you are willing to ship to in the "Ship To Locations" section.
2) Select either "Flat Rate Shipping" or "Calculated Shipping" in the section labeled "International".
3) Click the "Add an International Shipping Service" link in the "International Shipping Services section to add the details international shipping services you would like to offer.
I hope this helps. If you need any further assistance with your account, please feel free to contact our customer support team by mousing over the "Help" tab on our site and selecting the "File Support Case" option.
