Hi Community,
Update: It is not currently possible to add your eBay store referral ID to eBay store item links in your Auctiva store, however, this may be implemented as an option in the future.
Please feel free to check with us periodically by filing a support request using the appropriate link on our help page, http://www.auctiva.com/free-auction-software-help/help.aspx, and we'll be happy to provide you with an update if any new information has become available.
