The model cancellation form can be found here.
8.1 If the customer is a consumer and if he has concluded a contract with Monika Maria Wiesner at a distance (in particular via the online store) or outside of business premises for the purchase of goods, he may withdraw from the concluded contract within 14 days from the day on which he or a third party named by him and not acting as a carrier obtains possession of the goods, without giving reasons.
8.2 In order to exercise the right of withdrawal, the consumer must inform Monika Maria Wiesner (Sparkassenplatz 5/5, 6020 Innsbruck, firstname.lastname@example.org) by means of a clear declaration (e.g. a letter or e-mail sent by post) of his decision to withdraw from this contract. For this purpose, the consumer may use the model withdrawal form available on our website, which, however, is not mandatory.
8.3 If the customer revokes this contract, Monika Maria Wiesner will repay all payments already received, including delivery costs (with the exception of additional costs resulting from the fact that the customer has chosen a type of delivery other than the most favorable standard delivery offered), without undue delay and no later than within fourteen days from the day on which the notification of the revocation of this contract has been received by Monika Maria Wiesner. For this repayment, Monika Maria Wiesner shall use the same means of payment that the Customer used for the original transaction, unless expressly agreed otherwise with the Customer; in no case shall the Customer be charged any fees due to this repayment. Monika Maria Wiesner may refuse the repayment until the goods have been received back or until the Customer has provided proof that he has returned the goods, whichever is earlier.
8.4 The Customer shall return the goods to the address shown above without undue delay and in any case no later than within fourteen days from the day on which the Customer has notified Monika Maria Wiesner of the revocation of this contract. The deadline is met if the customer sends the goods before the expiration of the period of fourteen days. Without prejudice to the legal rights, Monika Maria Wiesner shall provide the Customer with a free return label for the return shipment. Monika Maria Wiesner shall send the return label by e-mail. The return shipment can be handed in by the customer in a parcel store of the respective provider in Austria and Germany. The customer has to pay for a possible loss of value of the goods only if this loss of value is due to a handling of the goods that is not necessary for the examination of the condition, properties and functioning of the goods.
