Much of the inventory listed on SeatGeek originates from the secondary market, which means the tickets were purchased at the venue box office and are now being resold. Since we allow sellers to price their tickets based on market price, you may see a discrepancy between the face value of the tickets and their price when listed for resale.
Sellers generally price their tickets according to demand, or according to what they predict demand will be. Consequently, tickets might be listed for more than face value if an event is sold out, or if tickets to an event are in unusually high demand.
On the other hand, tickets may be listed at a price that's lower than face value if there is little demand, or if there's a lot of inventory that hasn't been sold close to the event date.
