# My promo code isn’t working at checkout. What can I do?
If your promo code isn’t applying, try the following:
- Check the expiry date — some codes are time‑sensitive
- Ensure accuracy — double‑check spelling, spacing, and capitalisation
- Clear your browser cache/cookies
- Review the terms — some codes require minimum spend or exclude certain products.
If the code still doesn’t work, contact our team with the promo code and any error messages you see. Reach us via [**Live Chat,**](https://www.cos.net.au/) **1300 88 22 44**, or [**customerservice@cos.net.au.**](mailto:customerservice@cos.net.au)
