Abstract: During a marketing technique, lists of desired items and associated prices are received from multiple consumers. For example, consumers may provide lists of desired items and the (discounted) prices at which these items are of interest. By assigning the consumers to different price ranges based on the associated prices and an occurrence of at least one of the items in the lists, an aggregated interest in the item, including numbers of consumers that desire the item in the different price ranges, is determined. Information associated with the aggregated interest in the item is then provided to at least one entity that provides the item, thereby facilitating sales of the item to a subset of the consumers associated with one or more of the price ranges.
