In this gig, you'll get Elementor Pro and UA Elementor for just $3 a year.
Subscription is because Elementor doesn't offer any lifetime license and also offers only limited licenses. So, if anyone meets the target, they will stop renewing the plugin that will stop the updates for you.
But in this gig, as we keep on renewing the plugin, you do not need to worry about the plugin to stop working because of expired license.
