'ZDNET Recommends': What exactly does it mean?

ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.

Download a lifetime license to Microsoft Office at a deep discount with this deal.

Stack Social

If you need access to Microsoft Office but don't want to pay the yearly fee to access Office 365, you're in luck: Stack Social is offering a lifetime license for Microsoft Office Professional 2021 for Windows or Mac, starting at $40 (reg. $220) -- that's 81% off, and the lowest price of the year so far. Pay just once, and get lifetime access to Microsoft Word, Excel, PowerPoint, Outlook, Teams, OneNote, Publisher, and Access, no matter what kind of device you're using.

Also: The best Prime Day deals: Live updates

This deal gets you a one-time purchase to be installed on one device. You'll need Windows 10 or 11, or MacOS Monterey, Ventura, or Sonoma to download the software.

A caveat: While Stack Social is an authorized Microsoft partner and offers "lifetime" access to Office, it is possible that Microsoft could end the license. But the site has been running these Microsoft deals for years, and I can personally vouch for them -- I purchased an Office license from Stack Social about two years ago, and it's still working on my personal MacBook today. 

This deal won't give you the benefits of the latest Microsoft Office 365 subscription, either -- but you won't have to pay a $70 yearly fee to access Office apps, either. Windows users must have their OS updated to Windows 10 or 11, while Mac users should have at least Monterrey Version 12 or newer to download the software. 

Get Microsoft Office Professional for Windows or Mac with this deal today.
