Since the Acutiva listing has not posted yet, I owuld change that one to become a "test" post. Just leave it blank and change the title to TEST. (I think eBay even has a "test" category, but am not sure about that). Then I'd post the listing manually on eBay and be happy.
Then, if the Auctiva listing still posts, you'll only have lost 0.20.
Just a thought...
