i had a snipe recently that didn't go off... item id is:330609560558

i checked the snipe and the snipe time shows -127 seconds?... anybody know what happened?...

The original ending time of this listing was scheduled on September 9th (that's when you added the snipe), but seller changed or ended the listing earlier.
To avoid it in the future, you can place a minimum manual bid to restrict seller from changing listing's time.
