Calvin Klein Voucher Codes 2025

What You Need to Know

• Discount codes

  Can any Calvin Klein discount codes be used with sale?

  If you sign up to the newsletter, codes you receive directly from Calvin Klein and any special birthday vouchers you receive, can be used on sale orders.

  Is there a Calvin Klein loyalty scheme?

  Yes, Calvin Klein's loyalty scheme is called the Preferred Loyalty Program. Once you're a member, you can earn rewards by making purchases on the Calvin Klein website. These rewards will then be redeemed for discounts and savings on future purchases. 

• Student discount

  Is there a Calvin Klein student discount?

  Yes! Students, all you need is your valid student email address and you’ll get a lovely 10% off throughout the year. Remember, you’ll need to use a new Calvin Klein voucher code for each shop to keep getting your discount.

• Other

  My full-priced item has just gone into sale. Can I do anything?

  Yes you can my friend! If it’s been less than five working days since you bought it, give the customer service team a bell or email them with your order number - they should be able to give you a partial refund. If you don’t have time for that, simply return the items for a full refund, then re-order what’s now on sale if it’s still available.

  I’ve got my birthday voucher, can it be used on sale?

  Happy Birthday! Yes it definitely can. Your Calvin Klein voucher code will work on sale items if you buy direct from Calvin Klein and your total basket value is more than the saving you’d be getting from the promo code. Always check the terms of each discount code.

• Returns

  Can Calvin Klein sale items be returned?

  Yes and you’ve got a really long window to do so - 120 days!
