A ticket seller system can offer an enhanced event experience for users of the system by tracking the locations of ticketholders before and during an event to offer ticket resale and seat upgrade opportunities to the users. The locations of users can be harnessed to offer enhanced value to event attendees and to allow event owners to maximize the use of their venue during an event by offering new upgrades and resale options to patrons. Users who might miss an event and otherwise lose all of their ticket value can be detected, based on their location, and offered an opportunity to recoup some of the cost by reselling the tickets. Event attendees who desire to upgrade their seats at an event can be offered the opportunity to purchase upgrade tickets for seats that have been vacated by other attendees that have left the event while the event is ongoing.
