Useful tips and information

COS Voucher Codes

COS student discount

COS teamed up with various student platforms to offer 10% off the whole product catalogue. All you need to do to get the COS student discount is verify your student status through Student Beans or UNiDAYS. Simply copy down the code once you've received it and redeem it at the checkout.

COS birthday discount

On your birthday, COS will surprise you with a birthday discount code. The promotional birthday offer will let you save an additional 10% on the item selection in your basket. Make sure you've entered your date of birth, copy down the code, and use it at the checkout.

How to use your COS voucher code

You can upgrade your wardrobe at a discounted rate simply by using one of our COS discount codes. Take a look at our Voucherbox selection of active COS promo codes and copy down the code offering you a great price advantage. Next, place your fashion favourites and desired accessories into your shopping basket. Proceed to the checkout once you're satisfied with the selected items and paste the code into the field "Got a promotion code?". Click on "Add" to have the discount deducted from the order total.

What to do if your COS discount code isn't working

If you encounter an error code while using your COS voucher, check on the following:

  • You must transfer the COS code correctly to receive the promised discount.

  • The code must be valid at the time of your purchase.

  • Check if you've exceeded the minimum order amount of your COS coupon.

  • Look at the terms and conditions and ensure the code may be used by your customer group.

Can I benefit from any existing customer deals?

Existing customers have the opportunity to benefit from category deals. These are sales offers that let you save up to 30% on whole categories. For instance, you were already able to save big on men's t-shirts, a wide range of accessories, or the newest COS fashion collections for women. We recommend that you check our Voucherbox list at regular intervals to stay up-to-date about the newest deals.

COS first order discount

As a new subscriber to the COS newsletter, you will enjoy 10% off your first order. Look out for the "Subscribe" button and fill out the registration form with your email address. The COS first-order discount will automatically be sent to your inbox.
