You are using the Atlassian Marketplace and so, that's a topic between you and Atlassian. If you have some questions concerning purchasing, please contact sales@atlassian.com as Atlassian is my official reseller. Nevertheless, you have just evaluation licenses of my Gantt-Chart add-on listed on your screenshot and these are free of charge but limited to 30 days trials!
Kind regards,
Frank
