Seatwave
Seatwave is an online ticket marketplace for buying and selling tickets to music, sporting and cultural events. Ticket sellers list their tickets on Seatwave and specify what price they would be willing to sell them for. Buyers browse the site, compare ticket prices and can then purchase the ticket they feel is the best deal. Seatwave’s TicketIntegrity guarantee ensures buyers get the tickets they ordered by the day of the event. If they do not, Seatwave will find replacement tickets or refund the buyer.
