I've never been to primavera sound before and I have a question.
Just read here (https://www.primaverasound.com/en/barcelona/tickets-barcelona) "Shipping of wristbands: You will be able to ask for your wristbands to be shipped to you during the purchasing process. The cost of shipping will be 20€. We will get in touch with you from March 2020 in order to get your shipping address. The sending of wristbands will start in April 2020. Shipping only available for the European Union, the United States and Canada.".
What are these wristbands? What are they needed for? Why should I pay 20 more euros?
As I understand, my ticket is on DICE app on my phone, right? ("DICE protects fans and artists from touts. We’re a mobile app for iOS and Android. Tickets will be securely stored on your phone.").
Could you clarify this issue please?
