 As always, we’re also additionally offering **Friends Tickets**: People who cannot afford the Standard Ticket can instead request a Friends Ticket at a reduced price (the exact price to be determined individually in a conversation with the ticket team).
 
-We think it’s important to offer the Friends Ticket and the Up-and-coming Ticket. However, this will lower our average ticket price. For reference, we need to **average a ticket price of €180** to meet our budget. That’s why we’d like to ask you to buy the Supporter Ticket, if you can, despite the price hike compared to 36C3. And if your employer is paying for the ticket, please buy a Business Ticket (only Business Ticket owners will receive their invoice prior to the event). It’s only thanks to Supporter and Business tickets that we can offer Friends tickets in the first place.
