Hello,
The "scrolling" store window is set to appear at the top of each listing. However, you can put it wherever you'd like by inserting the store window html into the html description.
The store window html can be found at Auctiva -> Store -> Store Window -> Store Window HTML.
You may want to check out the "full" version of the store window, as it is set to appear at the bottom of each listing. To preview, go to Auctiva -> Store -> Store Window -> Edit Store Window.
HAPPY THANKSGIVING!
-Mike
