From 8 am ET today, Dell Home offers the Office 365 Home Premium 5-User 1-Year Subscription Key Card for Windows or Mac bundled with a $15 Dell Gift Card for $79.99 with free shipping. (No disc included; you'll need to download the software from office.com.) Assuming you'll use the gift card, that's tied with our expired Black Friday mention as the lowest total price we've seen. (It's a current low by $15.) It allows access to Microsoft Word, Excel, PowerPoint, OneNote, Outlook, Access, and Publisher and 1TB of OneDrive cloud storage.
