As Yahoo does not allow cancellation of bids on any auctions, we cannot accept any bid cancellations either, as you are bidding on live auctions with our Yahoo accounts. Once the bid is placed it is final.
One option that is available is to reduce your maximum bid and hope you are outbid. If you would like to do that, please contact us. If you still win the auction after reducing your maximum bid, you will still be charged for the auction and will need to pay shipping costs and our service fee.
