Today, Sunday, 28th of August, will be our final ticket sale at 18:00 CEST! We'll be selling tickets at the regular coder (€499 + Fee + VAT) and the late coder (€599 + Fee + VAT) rate.
To answer a frequent question: The fee is collected by our payment provider Amiando and I currently don't really know how high it is.
As we've been all along, JSConf remains to be a not-for-profit conference. Rest assured that we spend every single dime you give us on making that one weekend really awesome.
