Can I make use of the right of withdrawal?

Certainly! The right of withdrawal means that you can return your order within 30 days without statement of reason. Did you order something in June,July of August? Then you can return your items till the end of september! You can easily arrange this yourself in My Studystore. Select your order or part of it and click on 'Return'. You'll be shown what you have to do to return your order.
