Regardless of whether you set up new laptop or using a machine you’ve had for years, access to Microsoft Office is a necessity for many of us to get things done. Right now, you can buy one 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, one of the lowest prices we’ve seen.

The only major difference between Office 2019 and later versions is that it does not include Microsoft Teams. However, it does include Word, Excel, PowerPoint, Outlook, OneNote, Publisher, and Access — so if that’s all you need, it’s a good deal for the price. (If you want a version of Microsoft Office with Teams, you can check this offer for Microsoft Office Professional 2021.)

A caveat: While Stack Social is an authorized Microsoft partner and offers “lifetime” access to Office, Microsoft may terminate the license. But the site has been running these Microsoft offerings for years, and I can personally vouch for them — I purchased an Office license from Stack Social about two years ago, and it still works on my personal MacBook today.

This offer will not give you the benefits of the latest Microsoft Office 365 subscriptioneither — but you won’t have to pay a $70 annual fee to access Office apps either. Windows users must have their operating system updated to Windows 10 or 11, while Mac users should have at least Monterrey version 12 or newer to download the software.
