Tech Group Online via Amazon offers the Office 365 Home Premium 5-User 1-Year Subscription Key Card for Windows or Mac for $69.98 with free shipping. (No disc included; you'll need to download the software from office.com.) That's the best deal we could find by $19, although we saw it for a buck less last summer. It allows access to Microsoft Word, Excel, PowerPoint, OneNote, Outlook, Access, and Publisher and 1TB of OneDrive cloud storage.
