How to use a COSI coupon
- Choose an offer above and read its conditions. Copy the code if one is provided.
- Open COSI and add eligible items to your basket.
- For a code offer, look for a promo-code or discount field in the basket or checkout and apply the code. No-code offers may apply automatically; follow the offer instructions.
- Check the discount, delivery cost, and final total before paying.
Why might a COSI code not work?
A code can fail because it has expired, has already been used, excludes your items, needs a minimum spend, or is limited to a particular account or country. Check the offer details, remove extra spaces, and confirm whether another promotion is already applied. Try a different offer if the conditions do not match your order.
A past success is a useful signal, not a guarantee for every basket. After trying an offer, share whether it worked to help other COSI shoppers.
