A method and a system to communicate an alert to a mobile device are disclosed. The system receives, over a network, search information. The search information includes item description information that describes an item. The system repeatedly searches listings on a network-based marketplace to identify at least one listing that includes: an item that matches the item description information and is offered for sale in an auction on the network-based marketplace, a current highest bid for the item that is less than a price threshold, and a time remaining in the auction that is less than a predetermined time threshold. The system further communicates, over the network, the alert to the mobile device. The system communicates the alert responsive to the identification of the at least one listing.
