Trying to class it up, I guess. They used to just sent them in an envelope. I remember one year I got 6 individual ticket master tickets in a Cajuns envelope. Very ho hum.
I like what they are doing, though. It adds feels like you buying more and I'm assuming that other institutions are doing this also. Not just tickets, but a package with additional substance to it. Appealing to the part of the fan base that likes all the extra cool stuff and graphics. Kind of like all the social media improvements that have been made. I'm into it.
