Just in case some blues want to order via the official Website you need to follow these steps:
<a class="postlink" href="https://www.vfl-wolfsburg.de/" onclick="window.open(this.href);return false;">https://www.vfl-wolfsburg.de/</a>
1. Click on Tickets
2. Click on the VFL - City Fixture on the lower right corner of the page
3. On the right side click "Jetzt tickets für den Gästebereich sichern"
4. Click "Block 29" or "Block 33" for the standing Area (6 Euro), bottom of the page
5. Appliy the "tick" in the little square on the top of the website (basically just means that you accept the stadium rules and don´t plan to visit the guest areas as a Wolfsburg fan). Once you have accepted the rules there will be a new section on the lower part of the page where you can choose the amount of tickets you want to purchase from a drop down box. You should pick Normalpreis...You can get a reduced price as pupil, pensioner etc, however I am not sure if thats really worth the additional hassle at the turnstile as you would have to proove it there.
Once done with the amount of tickets click on "Zur kasse"
6. Now you need to register on the right hand side of the website via "jetzt registrieren". You need to fill out the formular now which is pretty self explanatory I guess. Provide your Mail address, a password, confirm the password, provide a user name, provide address details, provide a phone number.
Skip the rest of the check boxes until the Datenschutz one which you need to tick off. Then Click on the picture with the Wolf (its some sort of spam prevention) and finally on "senden".
I assume the next page is asking for the payment details (didnt try it out myself), but you should be able to handle that yourself. :)
Let me know in case of trouble!
