These are SECONDARY ticket prices for the most part. People are selling their seats, trying to collect on the assumption that TAMU will travel and it is by far the most attractive game on the schedule. Any time the big game on the schedule comes up, people are willing to move their tickets, in order to pay for their overall package. I've done that before. I have 4 club level seats, and friends that always have extras, so I sell my tickets, sit with my friends for the big game and in a lot of cases, the money I made paid for the entire season.
Dynamic ticket pricing makes a ton of sense, the school KNOWS that people are going to buy these seats and they don't want to sell them for cheap, knowing that a lot of people would put them right back on the secondary market, so they adjust to where the secondary market is.
