If you're fortunate enough to receive a ballot code for the Oasis reunion tour, here are a few tips to help you score tickets. First, keep an eye on your email, including spam folders, because ballot codes are often sent out at the last minute. Then, be quick on sale day, because tickets are sold on a first-come, first-served basis. Finally, don't try to game the system by using multiple browsers or tabs, because Ticketmaster can detect users trying to exploit the system and may reduce your chances or even lock you out of the queue.
