22. How long does a refund take?
For eligible voluntary returns outside the statutory withdrawal period, approved refunds are normally processed within 14 days after the returned goods have been received and the return has been approved.
Where an applicable statutory right of withdrawal is exercised, refunds are made without undue delay and no later than 14 days after we are informed of the withdrawal.
For contracts involving the sale of goods, reimbursement may lawfully be withheld until we have received the goods or the customer has provided evidence of return shipment, whichever occurs first, unless we have offered to collect the goods.
The receiving bank may require additional time to credit the funds.
23. How will I receive my refund?
Because our online store accepts Cash on Delivery (COD), eligible refunds are processed by bank transfer.

Refunds will be transferred to the bank account agreed with you.
We do not charge an additional refund processing fee.
24. Are original shipping charges refundable?
We currently offer free Standard Shipping (€0.00) to Germany and Austria.
As customers do not pay a standard shipping charge, there is normally no standard shipping amount to reimburse.
Where applicable law requires reimbursement of eligible delivery charges, we will comply with those requirements.

For orders delivered to Germany and Austria, we cover all applicable import-related charges, including:
