I was finally able to get it to work. Did everything but go through with purchase a ticket. A few notes:
1) Looks like there is a 10% discount for NARP members, Seniors, and Military
2) After entering passenger information, it takes you to the payment page. If you look at the top of the screen, you can go back and select seats.
3) The direction of travel on the seat selection page may be wrong. The Select coach is at the south end, but it looks like it displays it at the north end. Of course, I could be looking at it wrong.
