Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
Thank you for posting in Microsoft Office Community.
We understand your concern about the product pricing information of Microsoft Office 365.
The current version of Office is available as Office 365 subscriptions and Office 2013 perpetual license.
Buying an Office product depends on how many license you would like to use.
The Office 365 subscriptions can be purchased on a monthly or annual basis and the Office 2013 products are one-time purchases but it allows you to install on only 1 PC.
You may take a look at the link given below which provides the comparison between all the Office products available.

For further clarifications, reply and we would be happy to assist.
Thank you.
