I was told on an email that I need to reauthorize my account because there was a problem with it. I paid for the extra seconds just the other day and then I was informed that my sniping did not work. This was the message:
The last snipe we attempted to place for you failed, either because your authorization has expired, or it was revoked on your My eBay page.
As a safety precaution, although all of your snipes are still intact, we set the bid values to zero (0.00) in your sniping dashboard. This is to avoid any unexpected outcomes once you re-authorize, should you choose to do so.
If you'd like to continue sniping, please click to re-authorize your account.
We regret that we are unable to place snipes for you until this is corrected. Please note that most of the capabilities of the service, such as importing your Watch List, are dependent on the authorization.
Kind regards,
Your Friends at BidSlammer
