When a bidder receives the message "Bidding is Not Allowed" it means that the auctions credit card information is either not entered or has expired.
You can change this by logging into your manager account and going to Online Auction Setup > Online Auction Wizard > Step 4 > Change Credit Card. Please make sure that the information on this page matches the credit card billing information. Then click on Next.
*** Please Note *** After you enter your credit card information, the information will not remain on the screen. This is for your security. BiddingOwl.com does not retain credit card information.
