Certain sales have other requirements that must be satisfied before you will be allowed to bid.
Most sales in the U.S. require that bidders in other countries first submit a wire transfer deposit before they will be approved to bid. This deposit must be received in advance of the sale and can take several days to process, so we always recommend registering well in advance of the sale.
Other sales, usually those with items of exceptionally high value, require a deposit from all bidders which also must be wire transferred before the sale.
Some sales require bidders to provide certain documentation before bidding. Each sale may have a unique set of circumstances restricting participation.
Please don't wait until the day of a sale to register for it, as you may find that you're too late to satisfy all of the requirements to bid. Register early and be sure to read the terms of sale for each event, as well as the Standard Terms & Conditions of Sale.
