Hi Community,
We are aware that eBay just added the 30 day duration for fixed price listings today and we will be conducting a site update later this afternoon to add this option to the Auctiva lister page. This update will most likely take place by 6 PM PT today.
If you have any additional questions or concerns, please feel free to contact our customer support team using the web form on the following page of our site: http://www.auctiva.com/help/requesthelp.aspx
