I tried to make a couple of suggestions to another auctiva user today.
A couple of times I made the mistake of relisting it by accident from the closed listing section. Its a good idea to delete those as they sell. Of course that happened when closed listing could be bulk relisted.
Also check your auto relist profiles both on ebay and on auctiva.
Finally, if you have more than one quantity (assuming they are fixed price), they auto relist.
Otherwise its magic.
