Eventim.de is the official site for U2 tickets for the German shows. They just opened the pre-sale option. If you want tickets, it's now your chance to get a hand on them.
you do not need any pre-sale code from u2.com -- all they charge is a 5 Euro extra for each ticket. It's as easy as it can be, and for everyone who does not have a u2.com code or has used theirs already, this is the one and only chance to get face value tickets before they are gone within minutes during the public sale tomorrow :-) I just got my 2 GA tickets for Berlin, and life is perfect now :-D
