During checkout, in SELECT LICENSE OPTION section, you will have the option to choose between the annual subscription or regular one-time purchase. When you choose an annual license option, you are automatically qualified to receive 40% off when it’s renewed.
You will continue to receive product updates and bug fixes until your license is expired or canceled. The software with expired licenses will continue to work but no product updates or tech support will be provided.
It is recommended to maintain a valid license for live production applications. Did I mention all renewals entitle 40% off? :)
