StackSocial is selling Microsoft Office Professional for Windows and for Mac for $50. No subscriptions or monthly/annual fees are required.
Includes a "lifetime" license for one computer only. Let's unpack what that means. Office 2021 will be supported until October 13, 2026, so this "lifetime" license will include support and security updates for the next 4.5 years. After that day, the software will continue to work on the computer but at a higher security risk. According to the product description, the product will work on just one computer. When you want to install on another computer, such as upgrading to a new laptop, you will have to transfer the license. Also, this software is standalone, meant for one individual without cloud service and no upgrade path for future releases of Office. However if you want to view and edit documents from Word, Powerpoint, and Excel without using cloud services like Office.com and Google Docs, $50 for a license with 4.5 years of support is a hot deal.
After purchase, return to StackSocial.com within 30 days to redeem your purchase. View your purchase history, locate the Office purchase and copy the product key. Save the key for later. Click the "Redemption Link" button, sign-in to your Microsoft account, and apply the product key. Microsoft will provide links to download Office.
