Yes this is self serving - but I just received an email from a customer and thought I would share it with everyone.
Dear Ticket Brokers,
Thank you for giving me access to so many online ticket brokers. I called some local services out of the Yellow Pages - I thought the prices they quoted for the upcoming Cold Play concert was a bit much. After finding your site I was able to find great selection on StubHub.ca through your site. I would have not known of StubHub if not for your site.
Thank you -
