ABC Tickets is an independent ticket agency not affiliated with any box offices, promoters, Ticket master or Tickets.com.
They provide a service for people who want to see their favourite band or show. People who are unable to obtain seats for their favourite band because the event is sold out.
People want their seats to be 100% guaranteed, and want to deal with customer service representatives who can let them pick their seats, rather than choose "best available" and not even know what seat locations they are getting.
Finally, people just want premium seating to some of the best events across the United States, Canada and internationally!
