No, you do not need to enter your credit card information each time. When we ask you to enter your credit card information, it is just to make sure you are a real person and not a robot! You will have to register for each auction separately, but you won’t have to re-enter your credit card information. Please keep in mind that we do not automatically charge this card, so if you are the winner, you will still need to arrange payment with us. International credit cards are not accepted for any payments, but are accepted for identification when registering to bid online.
