If a nyrius.com coupon code isn't working, consider the following steps:
- Check if the product is already on sale or includes a free accessory, as additional discounts may not apply.
- Ensure only one coupon code is being used at a time, as multiple codes cannot be combined.
- Verify the coupon code's expiration date to ensure it hasn't expired.
- Confirm the coupon code is item-specific, as some codes may only apply to certain products.
