Ticket Office told me they would be sent via overnight mail on Friday. I guess we should get them no later than Monday (depending on our location to Durham).
This delivery gets later and later every year. This year, we'll get the tickets a day before the first (exhibition) game.
Now, the Ticket Office has moved into this century by allowing for electronic transfer and PDF scanning.
But the process must get better. Start earlier. Use a different printing vendor. Use less snazzy graphics on the tickets.
