I had a snipe for this item scheduled and it never activated - http://r.ebay.com/4364P3
I’d like to know what happens so I can prevent it in the future?

Hello,
We researched item 372356804055 as you requested. You did not schedule a snipe for this item. It was imported but no bid was ever set. In other words, the bid was set to zero (0.00). There are a few other snipes in your folder with zero bids as well.
Please let us know if you have other questions.
