COS Sales FAQ
When does COS have sales?
COS has several major sales throughout the year. The biggest ones are the Winter Sale (December 26 – Early February), Summer Sale (late June), Black Friday/Cyber Monday (late November), Friends & Family Sale (late April), and Private Sale (early May).
Newsletter subscribers get VIP early access to most sales, so sign up to shop the best pieces before they sell out.
How much discount can I get during COS sales?
Discounts range from 20% to 70% depending on the sale event. The Private Sale in May offers up to 70% off for VIP customers. Black Friday and Cyber Monday feature up to 60% off, while the Summer and Winter Sales offer 40-50% off.
Regular mid-season sales typically offer 20-30% off current season pieces. The deeper discounts usually happen during end-of-season clearance events.
How can I get a COS discount code?
Sign up for the COS newsletter to get 10% off your first order. Friends & Family Sales in April offer 25% off sitewide with promo codes like “COSFRIEND” or “FF25”.
Newsletter subscribers also receive exclusive discount codes throughout the year and get VIP early access to sales. This means you can shop the best styles before they're available to the general public.
Does COS offer student discounts?
Yes, COS offers a 10% student discount year-round. You can verify your student status through Student Beans, UNiDAYS, or Mecenat (depending on your region).
When is the COS Black Friday sale and what discounts are available?
COS Black Friday sale happens the last weekend of November. Expect discounts of 25-60% off sitewide. The sale typically starts a few days before the actual Black Friday date.
Cyber Monday follows with even deeper discounts up to 60% off, with the sale extending for a few days after. This is one of the best times to shop COS for their signature minimalist pieces at great prices.
What is the COS Private Sale and how do I get access?
The Private Sale happens May 3-7 every year, offering up to 70% off online-exclusive items. It's a VIP-only event for newsletter subscribers who get early access.
This is one of the best sales of the year with the deepest discounts on current season pieces. Make sure you're signed up for the COS newsletter before May to get your exclusive access code.
Can I use promo codes on sale items at COS?
Generally, promo codes cannot be combined with already-discounted sale items. However, the student discount (10% off) can be stacked with sale prices.
During special events like Friends & Family Sale, sitewide codes work on everything including sale sections. Always check the terms and conditions of each promo code to see if exclusions apply.
What is the COS return policy for sale items?
Full-price items can be returned within 30 days of purchase. Sale items can be returned within 14 days of delivery, unless marked “FINAL SALE” which cannot be returned.
How do I apply a discount code on COS website?
Go to your shopping bag and look for “Got a promotion code?” under the Order Summary section. Enter your code there before proceeding to checkout.
Make sure there are no extra spaces or typos. If the code doesn't work, check the expiration date and terms to ensure it applies to your items. Some codes only work on full-price items or have minimum purchase requirements.
Does COS have Boxing Day sales?
Yes, COS has a Boxing Day sale that starts December 26 with 40-50% off. This sale extends into the New Year, running through early February as the Winter Sale.
It's one of the best times to grab fall and winter collections at deep discounts. Items are marked down to make room for spring arrivals, so you'll find great deals on coats, knitwear, and seasonal essentials.
