All the plugins which are not free come under our EXTENDED License, so you don’t need to pay for their license to use them. Some of them might have messages requiring activation, but they are already activated on our side. No purchase code needed. When using them under our license you will need to wait for the plugin updates in our regular theme updates. If you want to be able to auto update them from wp-admin, you will need to buy your own personal license for that.
