Yeah that's what I figured too Wheels, makes sense
People charging for pre-sale links disgust me!
Arctic Monkeys had a good scheme going for their pre-sale. You got a one off code to access the pre-sale site based on your IP and e-mail address. This would allow you to only buy 4 tickets.
It still didn't work quite right, as it barred people on shared IPs etc, and it's not that hard to get around it all. But it was a step in the right direction.
