For those who are asking - I managed to get 2 return seats, Melb - Laun, travelling next July. At 5c each, plus $2 per seat if paying by credit card (how else do you pay?), the total cost for me was $8.20. It took a few tries to get to the end of the booking process as it kept timing out, but in the end it only took 10 min of my time. Not bad really.
