This is the latest version of the standalone Office bundle and gets you Word, Excel, PowerPoint and OneNote for any device running Windows 10 or a recent version of macOS. There's also 60 days of Microsoft support included at no extra cost.
This deal is all the more impressive considering Microsoft is still selling the software at its £119.99 RRP, while Amazon only dropped the price to its previous £108.90 on 26 September.
While the very latest features of Office apps are reserved for Microsoft 365 customers, the core Word, Excel, PowerPoint and OneNote experience is available without committing to a regular fee. See how the two compare in our Microsoft Office buying guide.
You'll have to be quick if you want to take advantage of this offer though, with the deal expiring by the end of the day tomorrow (14 October). It's just one of the thousands available on Amazon Prime Day, while you can find more of the best deals here.
