I had to call multiple times, and even go in person.
I thought the same thing that they were not being forthcoming, but in reality, I think it’s just that not many, if any do pop up.
I was able to purchase mine as I had bought it from a board poster here for years for a number of games, so they had me on record.
From what I was told, I think they hold a certain number of seats, back for different reasons, and always like to air on the side of caution.
However, if they see somebody has been going for years and have them in the system, I would assume they’re more than likely to be open to selling them a single, as opposed to keeping it in the house.
Same thing happened for wrestling, I finally was able to snag a single in the 100 level.
It’s definitely more fun going with people, but I would rather sit in really nice seats and go by myself then go with somebody and sit in a seat that I don’t want to be in.
