When the bid button is gray, this can mean one of two things.
One: You are pending the auctioneer's approval.
Each auction you register for requires the auctioneer approval before you can bid. Upon registration you will receive an email notifying you that your approval is pending. Once you have been approved for the auction, you will receive a second email to notify you of the change. All approval is handled directly by the auctioneer and typically takes 24-48 hours to complete. To expedite the approval process, you will need to reach out to them directly.
The auctioneer contact details can be found on this same page by clicking View Auction Details.
Two: The auction is not yet live.
Each live auction must be live before a bidder can join it. The auction will typically be set to 'Live' roughly 2 hours before the auction begins.
