I’m trying to enter a bid and I get a window that says update my preferences and when I enter my email address the window goes blank. Can you help me with this?

Hello David,
Thank you for your question about the message about updating preferences. I think you are referring to the authorization. Just go to https://bidslammer.com/user/prefs/ and follow the prompt to "log in with eBay." That should solve your issue.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
