I had 8 on mine (a Monsoon dress) and one decided to bid yesterday night finally, it still has 2 days to run.
So a sale, but mightnot reach what I think its worth yet.
However Dh has an ebay shop and often sells items with no watchers on a last minute bidding war and items with over 30 on no sale at all- its totally unpredictable (and at least 1 watcher probably has someting similar and is wanting a price estimate is my guess)
