Bidslammer indicates bid was placed and that I won. Ebay shows no bid was placed

Hello Randy,

What item number? We will investigate for you.

Kind regards,
BidSlammer Customer Care

As I suspected, this snipe occurred on Dec 6 at 5:30 PST. During that time eBay was down for about 45 minutes; at least, all snipes returned a "site unavailable" error. That's why all your snipes before and after on the same day all passed. Rest assured we were working ok though.
