Hi Silly,
This is how I understand it:
Auction style listings with no Buy-It-Now option will be shown under the "Auctions Only" link.
Auction style listings with a Buy-It-Now option OR fixed price listings will be shown under the "Buy It Now Items" link.
eBay Store items will be shown under the "Store Items" link. (The Auctiva Store, however, is a completely different entity to an eBay Store as it can feature a combination of all three listing styles).
If I'm wrong, I'm sure someone will put me right...Hope this helps
Bonnie.
