To my knowledge, Microsoft Office Home and Student 2013 is a one time purchase and not a subscri. Home > Software > Microsoft. You will then be able to download the ISO of the install. They want you to just download the installer files over and over for every computer you want to install it on, or use their 'Deployment Tool'.

The Office 2013 Professional Plus as well as Project and Visio downloads require a retail product key. They can also be activated for a 60 days’ trial period with a trial key that is available from Microsoft free of charge. These are the full standalone (offline) installers that don’t have to download the entire application from the internet when being installed.
