After each order you will receive a 5% voucher (if you order more then Euro 50,-). This voucher is valid for 8 weeks. If you use the voucher for ordering and you order more then Euro 50,- you will again get a new voucher and again valid for 8 weeks. This way you get a 5% discount on every order.
If we have a discounted product the voucher will work as well. You cannot combine vouchers and each code can be used once.
In the shopping cart, under the payment methods, you will find the field where you can enter your voucher code. After entering the code and pressing the "OK" button, the discount will be applied.
