In order to fit everybody's means, the price for the tickets is basically pay what you want. On the one hand, if you are a student, unemployed, or similar we don't want the ticket price keeping you from attending, and on the other hand, if you earn decent money and want to support the Rails community, we want to provide you with a simple way to offer a little bit of extra support.
For regular participants we suggest a ticket price of at least 25€. If you lack the money just pay less, and if you can afford it, why not chip in 50€ for an even better camp? It should be noted that this is a strictly non-profit event, so all your money goes into the event, and if there's any surplus, it will go to the Ruby Berlin e.V. to further support the Ruby/Rails community.
