If your current version of Office is starting to feel a little old, this might be the right time to upgrade without committing to a subscription. Microsoft Office Professional 2021 for Windows is down to A$51 on StackSocial—marked down from its regular A$322 price. It’s a one-time purchase with a lifetime license for one Windows PC. Just note that the license ties to your device, not your Microsoft account, and must be redeemed within seven days. This version covers all the core apps: Word, Excel, PowerPoint, Outlook, Teams (free), OneNote, Publisher, and Access.
