We're experimenting with a fresh approach. In instances where we're uncertain about the appropriate sale price, we're giving our viewers the power to determine the value through a "sealed bid" process. Your bid remains confidential, as does everyone else's. You're permitted a single bid, which is final once submitted, so consider your offer carefully. These special deals are time-sensitive, so if you really like the piece(s) being offered, don't hesitate to place your bid. When activated, each bidding session concludes at 9pm, Mountain Time.

It's a similar concept to eBay, but without the additional charges.
