eBay has added a new notice page (regarding Hurricane Sandy and possible shipping delays) to the bidding process that is holding up our sniper engine and preventing snipes from executing.
A few aren't getting the notice and are executing ok. I don't know if it has to do with the item location, your location, or what.
Our coder is working on it now, hopefully it will be ok in a couple hours.
Until it is, any snipes scheduled to execute most likely won't. So, you should make other plans for your bidding until we've updated for this new notice.
We're very sorry for the trouble and missed snipes.
I'll post again where there's some more news.
