Do you have an active eBay store? If so, you can automatically sync all of your fixed price listings from eBay.
Simply go to this page and click the 'Enable' button, and you'll be brought directly to eBay where you can approve us to sync your listings.
Once you enable the sync, all of your current applicable items will be imported, and any updates you make, or new items you list on eBay, will automatically be brought over.
From there, you'll find advanced settings for your sync.
