Validation
When a coupon code is submitted, validation checks that the code is valid and can be applied. If the code does not exist, the field fails with the message: “Coupon code: is invalid."
If the code exists but cannot be applied. For example, because the usage limit has been reached or the coupon is no longer active, validation fails with a message describing the reason.
If no coupon code is submitted, validation is skipped.
