Hi achesterman,
Welcome to Auctiva!
The Auctiva store that was created for you automatically when you signed up for Auctiva will display all of your active eBay listings at any given time and can be reached by clicking the link in the bottom-right of your scrolling gallery. There are a variety of ways you can customize the appearance of your Auctiva store, which can be found under the "Store" tab within your Auctiva account.
Having an Auctiva store will not actually change the appearance of your eBay listings at all. When a customer clicks one of your items in your Auctiva store, he/she will be taken to eBay to purchase the item and the auction will appear the same as if the buyer accessed the listing through an eBay search.
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:
