Looks like the mid level is now splitting the tickets up too. If you ask for 4, mine showed up as 2,1,1. Logged out, tried again, and it was 3,1.
How can you tell if they are all together or split? A friend sent me their e-mail they got from NCAA and I created an account and it appears I can purchase with no problem while getting to the payment page. But I don't see anything regarding tickets together or splitting.
