Because I am late I can only order tickets for Nimwegen via e-mail, ticketmaster says. Never done that. How does it work. Do I print my own tickets? Does it take longer to get in with those - any experiences? Thanx.

It's like ordering books at amazone. You have to pay with your credit card (€ 93)and then you'll receive an e-mail and you have to print your ticket. It is easy.
Buuut:

I'm absolutely sure, that you can buy tickets before the show for less than € 93.

i bough mojo tickets for the who,

you get an email with a barcode, print it out and they will scan it.. just the same as a normal ticket

so you can collect the barcodes from now on ;-))

I have done this with Red Hot Chili Peppers tickets and New Model Army tickets. After the show you can exchange your printout at the box office at the location fo real hardcover tickets!
