Tips for Saving More on Your COS.com Order

Why isn’t my COS discount code working?

There are several possible reasons your COS promotional code may not work: the code might have expired (many are time-limited), it could only apply to selected items or require a minimum order value, or it may have been entered incorrectly—be sure to check for typos, case sensitivity, or extra spaces. Always review the terms and conditions of the code. If you’re still having trouble, try a different code or check COS.com’s promotional banners for current offers.

How can I get a discount code for COS.com?

COS often offers a discount for first-time customers who sign up for their newsletter—usually 10% off your first order. You may also find codes during seasonal sales or special events. Following COS on social media or checking trusted coupon platforms can also help you discover active promo codes.

Can I use multiple COS discount codes on one order?

No, COS only allows one promotional code per order. If you have several, choose the one that gives you the best discount.

Do COS promo codes apply to shipping costs?

Typically, COS discount codes apply to product prices only and not to shipping fees. However, COS occasionally offers free shipping promotions, either automatically on qualifying orders or via specific codes. Check the promotion details before applying your code.

Are there general COS discount codes or only for specific countries?

Some COS promo codes are region-specific and may only be valid in certain countries or currencies. Always check that the code you’re using is intended for your shipping location. General discounts like the newsletter signup offer are usually available across most regions COS operates in.

How to use a COS promotional code:

Start by browsing COS.com and adding your favorite fashion pieces to your shopping bag. Once you’re ready to place your order, click the shopping bag icon at the top right of the screen to review your selected items. On the right-hand side of the checkout page, look for the field labeled “Type your code” under the “Enter the COS promotional code here” section (as shown in the image). Enter your promo code in that box, click “Add”, and verify that your discount has been applied to the total before proceeding to checkout.
