My jury is still out on whether the eBay store inventory format is worthwhile considering the auction insertion fees for media are lower than standard item insertion fees.
Lower insertion, higher FVF are ok for lower value iems if the items are actually found in the first place !
P.S. SIF are searchable once the buyer has found where to set it up, something like two levels down on the search customisation setup. In otherwords eBay only want auctions and know that most buyers will not either know or be able to configure thier searches that well.
