COS Black Friday 2026

As of 2 November 2026, COS has not announced its Black Friday 2026 sale in Ireland. Its Black Friday page says the offer is coming soon, launching in November, and will be available on cos.com and in stores. Black Friday falls on Friday 27 November 2026 and Cyber Monday on Monday 30 November 2026. This page and the COS discount codes above will be updated once COS announces its sale.

COS Black Friday 2025

	COS Ireland, 2025
Event	COS Black Friday 2025
Headline offer	20% off sitewide, exclusions applied

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

COS Returns and Offer Rules

The 2025 Black Friday offer of 20% off sitewide came with exclusions. COS's Black Friday FAQ refers shoppers to its standard returns policy rather than separate Black Friday terms, and says exact discounts may vary between online and in-store.

Check the exclusions and returns policy COS shows for 2026 before you order.

How to Save at COS on Black Friday

Watch the COS Black Friday page during November, as COS says the 2026 offer is launching that month.
Compare the online price with the in-store price, since COS says discounts may vary between the two.
Check the exclusions before checkout, as the 2025 sitewide offer did not cover everything.
Compare the sale price with any valid COS discount code before you pay.
