Once a bid is placed it cannot be canceled in any circumstances. Bids are automatically placed on the Yahoo Japan Auctions and cannot be retracted. Please ensure you review all the bid details before placing your bid.
If you wish to increase your bid, you simply place another bid with the higher amount. However, you will require the additional funds to place your second bid at the current time. The shipping method and address details can be updated at any time before your order is shipped.
