@arudy There was a presale until a few days ago, announced to ticket buyers by email, in a blogpost and on social media. It's closed now, but we will also sell additional stock for cash at our merch desk during the event. There's usually a queue though, and many size/color combinations sell out quickly. Bringing your own garment and finding someone to press or embroider it is a common alternative to the "official" merch. Happy hacking :)
