An apparatus, method, and program for pre-selling tickets to determine whether to book an event or activity, and for facilitating the sale of those tickets. Consumers who pre-purchase a ticket are plainly notified if an event has not yet been booked. They are also shown the progress toward the likely booking of the event. A successful pre-sale of tickets triggers the booking of the event. An unsuccessful pre-sale results in the event not being booked. Consumers who help effect an event booking may be given privileges over those who purchase traditional tickets for the same event after it has already been booked.
