These General Terms and Conditions (GTC) apply to all deliveries from WI23 to consumers.
A consumer is any natural person who enters into a legal transaction for a purpose that can predominantly be attributed neither to his commercial nor to his independent professional activity.

Contracting party

The purchase contract is concluded with Paderborn University (UPB). Pursuant to Art. 20, 21 BayHSchG, UPB, as a state institution and self-governing body under public law, is represented externally by the President.

Conclusion of contract

  • The presentation of the products in the online store does not constitute a legally binding offer, but only an invitation to order.
  • By clicking the button [Buy/order with costs] you place a binding order for the goods listed on the order page. Your purchase contract is concluded when we accept your order by sending an order confirmation by e-mail immediately after receiving your order.


  • The registration for participation is binding.
  • Cancellations must be indicated by e-mail to
  • Should you cancel your registration up to 30 days before the start of the event, 75% of the fees will be refunded. In all other cases, your financial obligations remain fully valid.
  • In exceptional cases, you may designate a person to attend the conference in your place. Should you wish to make use of this option, you must notify us by letter or e-mail no later than 7 days before the conference.
  • The registration fee is due immediately upon registration, payment is only possible by credit card.
  • The right to participate is subject to full payment of the registration fee.
  • We reserve the right to change the conference program.
  • If the event has to be cancelled for reasons of force majeure, your fees will be refunded. There are no further obligations of the organizer towards the participant. On the other hand, registrations remain valid if the event has to be postponed.
  • Important: Please do not cancel your payment yourself via the credit card used, as you will then have to pay considerable fees for “chargebacks” (usually around 40 €), whereas a refund by the organizer is usually free of charge. Most of the time you will even get back the payment/banking fees. If you have already cancelled your payment in this way, we ask that you reverse this cancellation so that we can refund the payment.
