COS Promo Code

COS Promo Code

A COS promo code may be available through welcome, email or other selected campaigns in Ireland. Availability, discount value, customer eligibility and product exclusions can change, so check the current offer terms before ordering.

COS also runs seasonal sales and limited-time promotions. Whether a code applies to sale items or can be combined with another benefit depends on the specific campaign, so compare the final basket price rather than assuming a fixed welcome discount.

Why Your COS Promo Code Isn't Working

A COS discount code may not work due to specific restrictions or conditions.

• The COS code has expired or the promotion has ended
• Selected products or collections are excluded under the offer terms
• Customer, channel or minimum-order requirements are not met
• The code conflicts with another promotion under the specific campaign rules

How to Compare COS Promo Codes and Sale Prices

COS savings can come from direct sale prices, student offers and limited-time promo codes.

• Compare the current product price with any eligible promo code.
• Check whether the selected item is excluded from the promotion.
• If you are eligible for a student offer, compare its final price with the active public promotion.
• Confirm whether the code can be used on a sale item under the specific terms.

Use the final basket total as the comparison point before placing the order.
