OKTAN

Eight races and complete freedom: what, where, when, and how.
The OKTAN voucher is a package that gives you total freedom of choice: Intro (¼), Recruit (½), Night Recruit (½), Runmageddon, or even Runmageddon Hardcore – mix it up as you like.
Pay once, and then just decide where you hit the mud.
An option for those who don't know the word "stop."
