Make sure your birthday voucher code is valid and follow the rules of the game:
You can only use your voucher on the official website of Calvin Klein
The voucher code only works if the total order amount exceeds the value of the promo code
It’s a non-refundable nor replaceable code in case the order is (full or partially) returned
It’s also good to know that:
You can enter your code by clicking on ‘Enter your promo code’ in the shopping bag page and then click on ‘Apply’
You can only use one promo code per order (unless stated differently)
In case of returns, the promotion code value will be proportionally split across the ordered items
Your birthday promo code can be used in combination with sale
