dunno if you know, but before you try to relist, ALWAYS go to my ebay and check to see if listed (also check your email for listing notices from ebay, because doesnt always show up immediately in my ebay)
reason i say that is because sometimes you get an error msg when it actually listed. this is especially true for a particular error msg that ebay is generating for all 3rd party listing services
