PLEASE clarify this for me

Your auctivia store mirroes every thing listed on eBay, regardless of what format it is. You can edit with shows in your Auctiva store and what doesent.

as far as store listing....
At the top of your listing template is where to select to put items directly into your store. Select Store format. This will place the item directly into your eBay Store.

Here is the text from the help button about that:

How do I use it?
* Choose what kind of listing you would like, and mark the circle next to it.

Auction Format - You set the opening price and the buyers bid on the item until the auction closes. This format is great for unique items.

Reserve Price - This is the minimum amount you will accept on an auction. You set this price to protect your item from selling too low. If the auction does not meet the reserve price, it will close with no winner and you can relist it.

Buy It Now - A set amount where a person may buy an item immediately, bypassing the auction format.

Fixed Price Format - Your product sells at a specified price pre-determined by you (BIN price = Buy It Now.) Make sure to do research into current market value for your item.

Store Item Format - Your product is featured in your eBay Store and sells at a specified price pre-determined by you (BIN price = Buy It Now).

To get to the place to edit what is shown in your Auctiva Store(eBay mirrored),
select the Store tab, manage (towards bottom), select Store Items.

I hope this helps!
