Each site has a different ticket sales link (this is to keep finances and tax separate for different countries). You do NOT need to buy both an online-remote ticket AND a site ticket, you choose either one: buy an online-remote ticket if you intend to do DEATHCon from the comfort of your own home, OR buy a site ticket if you intend to travel to that location and attend in person All the cities are on sale now except for Bonn. Bonn got overcome by Germany paperwork bureaucracy and will be hosting in 2025 instead of 2024.
