Yeah, I had a category 1 ticket to the final which was US$900 cost price.
I booked TST7 tickets a year ago which follows a team (Australia) from group stage to the final, with that team replaced by whoever beats them, and then whoever beats them and so on. They were about US$3200 from memory. I bought a few scalped tickets to see Brazil, Argentina and Spain in the group stage which cost about US$100 each.
