How to activate a COS promo code

Open the online shop and learn which COS styles are now up for grabs. You may see the latest collections, or some older items that you can get at much less. Simply keep browsing the store until you find the style you wish to purchase. Click on its preview and choose the right color and size before pressing the ‘Add to bag’ button. Do the same for as many clothing pieces and accessories as you like, then proceed with reviewing your shopping bag.

Within that new page, there’s the option to add the COS promo code you want to use to your order. It’s labelled ‘Got a promotion code?’ and you just need to click it to reveal an empty text box. Copy your code right there and confirm its use. The total price should change right away, meaning that the coupon worked and you can finally proceed with checking out.

Where to get more COS promotions

If there is a COS promotion going on, it will be advertised with images and alerts on the front page of the online shop. Clicking on either option will redirect you to the part of the website where the discounted items are shown. Meanwhile, if you see a code copy it in your clipboard and then use it later during the cart review step.

You can also keep an eye on all of the latest COS offers by joining the mailing list. With the newsletter you’ll be able to stay in the loop and learn everything about the latest collections and deals, including some exclusive codes for COS that you can use later.

COS discounts with no codes: other ways to save money

Whenever it’s not possible to take advantage of any COS promotional code since there are none available, you should wait for some Sale events. The best ones usually pop up during any season change, Black Friday and the end of the year. That’s when most items can be bought at a much lower and accessible price. Just wait for the special alert sent through the newsletter to get more information about those promos.

Another great benefit of purchasing clothing at COS is that you can enjoy COS free shipping whenever you spend at least $150 on any order, no matter which items you are going to get.

Common problems when applying a COS discount code

Can’t make your COS discount code work? The first thing you should do is read the terms of use set by the company, as there can be some requirements you are not aware of. For example, the code you have might only apply after you have added select styles to your shopping bag. Meanwhile, others could be available exclusively for first-time customers.

Then, you should also read the COS promotional code a second time right after writing it down in order to fix any mistyped characters. It’s quite a common problem that can be easily solved, simply by looking at the text box to remove any extra spaces and change the wrong letters.

Don’t forget to make sure the code for COS you are using is still available too. Each coupon will be gone after some time, so use it before that happens or you will have to hope there’s another one still up for grabs.

COS FAQ - other useful information for you

• Does COS offer student discounts?

Yes, you can scroll down to the bottom part of the store’s page to see the ‘Student Discount’ section. Open it and see which COS student offers are available through the Student Beans platform. You’ll be required to create an account and verify your ID first.

• Is there a COS first order promo code?

Yes, you can get it by subscribing to the newsletter right after entering the website, through the alert that will immediately pop up on the screen. Remember that it also has some terms and conditions you need to follow in order for the code to work as intended.
