Cheffin Onderkin Rumag shirt

I just keep getting blank pages when I click Buy on any venue? So confused. I live in Indiana, the Chicago one in on a weekend but when I go to the Wabash In one it’s like I am buying tickets to a venue.  Really should have made that known before people bought tickets. Still can’t wait for the show though. I did the merch bundle ticket for the Seattle show but it doesn’t ask for t-shirt size so do we just get a random size shirt or will we be asked later down the road what sizing we want?
