Where to enter your COS promo code
COS is part of a larger fashion group whose brands share an account system but run separate promotions, so a sister-brand code is refused here. Its sizing runs generously and differs from the group's other labels.
Sister-brand codes do not cross, even on a shared account. The promo code field is at checkout with the order summary. The group's brands share an account system but run their own promotions.
