Get the iOS app Get the Android appYour COS promo code might not be working because it has expired, was entered incorrectly, or doesn't meet the specific requirements for the discount. Common reasons for rejection include typos, not meeting a minimum purchase amount, or trying to use the code on items that are excluded.
Double-check that you've typed the code exactly as it appears, paying attention to capitalization and special characters. See if the code requires a minimum spend or applies only to certain product categories. Some codes are time-sensitive and may have expired. If you're using a student discount, make sure you've authenticated through Student Beans. Most COS promo codes can't be combined with other offers.
Pro tip: Try removing the code and re-entering it, or clear your browser cookies and restart the checkout process to fix any technical issues.
You enter your COS promo code on the shopping cart page, before you enter your shipping information. The promo code field is in the "Order Summary" section of your shopping bag.
To use a promo code, add your items to your bag and click the shopping bag icon. Then, click "Go To Shopping Bag." In the "Order Summary" section, find "Got a promotional code?" and click it to reveal the input field. Enter your code and click "Add" to apply the discount. You'll see the price change before you enter your shipping details.
Pro tip: Take a screenshot of your applied discount before proceeding to checkout. This can be helpful if you need to contact customer service about any issues with the promo code.
COS generally allows you to apply promo codes to sale items, but you can't use multiple coupon codes in the same transaction. Student discounts through Student Beans can be used separately but usually not with other promo codes.
You can sometimes use coupons on top of sale items at COS for extra savings during sales. However, you're limited to one promo code per order. To use a different code, you must remove the one already applied. Student discounts of 10% are available year-round through Student Beans, but they are usually separate and can't be combined with other promo codes. New newsletter subscribers get a 10% discount code for their first purchase, which has the same limitations.
Pro tip: If you have multiple promo codes, calculate which one gives you the biggest discount on your order before applying it, since you can only use one at a time.
COS promo codes often exclude new collections, collaboration items, and certain premium or limited-edition products. Specific exclusions vary and are usually in the terms and conditions.
While there isn't a list of product categories that are always excluded, it's common for high-end items, brand collaborations, and new collections to be excluded from discounts. When using a promo code, check the terms for your specific code. If the discount isn't applying to certain items, they are likely excluded. The best way to confirm exclusions is to check the fine print or contact COS customer service.
Pro tip: Shop the "Sale" section on the COS website first, as these items are more likely to be eligible for additional promo code discounts.
If your COS promo code shows as expired even though you recently received it, check the expiration date in your original email or promotion and contact COS customer service for help.
COS promo codes usually have expiration dates, some lasting only a few days and others several weeks. If a recently received code is showing as expired, first check the expiration date in the original email. Technical issues can sometimes cause codes to be rejected by mistake. You can also check sites like SimplyCodes, which tracks code success rates. If the code should still be valid, contact COS customer service through their website with details of when and how you received the code.
Pro tip: Sign up for the COS newsletter to get a 10% off promo code for your first purchase, which can be a quick fix if your current code has expired.
