These were last year's terms, and COS's 2026 offer can differ.

COS Black Friday Returns and Offer Rules

In 2025 the Black Friday discount was applied automatically at checkout online, so no code was needed. The offer applied to garments marked with a red price online and excluded COS gift cards, and further exclusions applied.

COS said its Black Friday offer would be available via cos.com and in stores, and that exact discounts may vary between online and in-store. For returns of Black Friday items, COS referred shoppers to its returns policy, and during the 2025 sale its menu linked to Extended Returns. Check the returns policy COS shows for 2026 before you order.

How to Save at COS on Black Friday

  • Sign up to the COS newsletter before the sale: COS says subscribers are the first to know and get 10% off their first order.
  • Look for red prices online, since the 2025 discount only applied to garments marked with a red price.
  • Compare online and in-store prices, because COS says exact discounts may vary between the two.
  • Remember that COS gift cards were excluded from the 2025 offer.
