Have used iticket a few times for events and have not had a problem. Tickets arrived on time and the online site is easy to use and good value. The emails sent out about upcoming events is great info as well.
Good service all round.
These guys just make it so simple to buy tickets and select seats. And they don't charge a fortune for delivery either. Whenever I use other sites I get so frustrated that they're hard to navigate, compared to iticket. I had a tricky situation where I had to amend a booking too, and the person I dealt with on the phone was friendly and efficient and nothing was a problem.
