As I mentioned, I had no trouble with it - a few of my friends buying tickets had no problem at all. Considered it could be a problem at your end?
All things are possible. It may have been from my end.
Although, I was able to buy Manly v Tigers tickets through Promaster 5 minutes prior.
Also Collingwood v Nth Melb through Tiketek 2 minutes after I gave up on the Manly Cowboys game.
Haven't tried again since, although I will when I get home. I know the game won't sell out and I will get my tickets, but...
My point remains though. If a casual fan makes a decision to buy tickets to an NRL game and finds broken links on the NRL website, inconsistent dealings with the Tiketek website, and it's all too hard, will the CASUAL FAN keep trying. I couldn't find a link to the tickets section anywhere on the Manly website this morning. I am no internet genius but I think that I go ok.
All I am saying is that it should be an easy option for weekend entertainment, if the casual fan wants to cough up their dough. Especially 2 weeks in advance!
