Yes, renewal discounts are available and are applied automatically before payment. But you do need to renew your license BEFORE the current one expires.
Note that when renewing early, you do not loose any days from your current license. The new license date is calculated from the current license expiration date.
If, by any chance, your license expired and you missed the deadline, contact us and the decision to give you a discount will be reviewed for your case. Upon approval, a partial refund will be made after a purchase at full price.
