Funny that. I just made a comment on another thread, where ticketek are charging $6 handling fee per ticket. The Bulldogs had a promotion for 1988 prices into the game, and were charging $10 for a GA ticket, mates went to buy it, but once they realised it was going to cost $16, they just decided it would be better to buy them at the gate, and make sure the weather was good.
It also might be one way of getting free public transport to games, if the NRL could spread the cost of that element around all the tickets and negotiate with each state govt to a fair price. It would also mean that people would commit to going to the game earlier cause they need to prepurchase a ticket to take advantage of the free transportation to the game.
