Carl Cox this year:
Before 9pm- 20 Euro - 10 with a flyer.
9pm-11pm - 30 Euro - 20 with a flyer.
After 11pm - 45 Euro - 40 with a flyer.
Look around on the tuesday for Carl Cox reps- it's not that hard to get flyers.
WLS - You can get reduced rate wristbands from reps with no passout. I couldn't find any when I was there though and didn't fancy paying 55Euro for the full ticket so never went...
Hope this helps!
