You can buy a lifetime license to the 2019 version of Microsoft Office Professional Plus for either Windows or Mac from Stack Social for $25 - that's 89% off.
The only major difference between Office 2019 and later versions is that it doesn't include Microsoft Teams, but it includes Word, Excel, PowerPoint, Outlook, OneNote, Publisher, and Access, making it a great deal if that's all you need.
While Stack Social provides 'lifetime' access to Office, Microsoft could possibly end the license. However, the site has a history of offering these deals for years, maintaining reliability.
The deal doesn't provide access to the latest Microsoft Office 365 subscription, saving users from paying a $70 yearly fee. System requirements include Windows 10 or 11 for Windows users and Monterrey Version 12 or newer for Mac users.
