Abstract: A method implemented by a first party to facilitate a sale by a second party of at least a subset of a set of items includes contractually committing, at a first time, to the second party to purchase title in the item subset, generating a displayable user interface accessible over a network to the second party, the user interface operable to allow the second party to input information describing the items, receiving the information over the network, and issuing via the network, at a second time of the first party's choosing and subsequent to the first time, a purchase order to the second party for the item subset. Alternatively, the purchase order may be issued by the second party at a second time of the second party's choosing and subsequent to the first time.

Abstract: A system includes an electronic device coupled over a network to first and second computing devices. The electronic device is configured to serve to the first computing device a first web page displayable on a display device. The displayed first web page includes a user interface operable to solicit from an individual of a plurality of individuals a current prediction of a plurality of current predictions of market prices of a product. The electronic device is further configured to determine an accuracy rating for each individual of the plurality based on a correlation between previous predictions provided by each said individual and actual market prices of the product. The electronic device is further configured to assign to the product a price estimate associated with a first predetermined time interval, the price estimate being a function of the accuracy ratings and current predictions. The electronic device is further configured to determine a current sale price based on the assigned price estimate.
