Placing an AutoBidMaster Security Deposit is not a charge, but a temporary authorization hold on a credit card that appears in the form of a pending transaction. This hold lapses every 30 days and must be renewed to continue bidding. When the Security Deposit expires your buyer power will be set to zero and you will need to place a new Security Deposit.
Security Deposits made by wire transfer, however, remain in your account until you request a return or choose to apply it to applicable fees and purchases.
