We can only store addresses associated with your cards at the moment. To inform an auctioneer of an alternate address, in the case of delivery, you will need contact the auctioneer or delivery company at directly at the time of invoicing. They might ask you for proof of that delivery address, just to be sure it gets to you.
If you're having your items delivered via our partner, Auction Logistics from Mail Boxes Etc., you can change your delivery address during the delivery checkout process. For security purposes, you may still need to provide proof of that address to the auctioneer and Auction Logistics from Mail Boxes Etc.
