Hello. I got a message from bidslammer that says my ebay authorization has expired and I need to log on to ebay to reauthorize. I contacted ebay and they suggested I need to do it on bidslammer. They did not know how to reauthorize.

Hello Michael,
Thank you for your question about your authorization. You re-authorize using the link given to you in the email message. Or, you can go to BidSlammer Preferences, and follow the instructions there.
If the authorization step does not resolve your issue, please let us know, and we can take the next step.

That seems to have worked. Thank you!

You are quite welcome. Good luck sniping!
