If the harkla.co coupon code isn't working, consider the following steps:
- Check the expiration date of the coupon code.
- Ensure the code is valid for the items in the cart.
- Verify if the code is for first-time purchases only.
- Confirm there isn't an automatic discount applied during a sale, as a second discount code cannot be used.
- Contact [email protected] for assistance and a new code if necessary.
