E-Techgalaxy via eBay offers a Microsoft Office 365 Personal 1-User 1-Year Subscription for Windows and Mac for $29.99 with free shipping. That's the lowest total price we could find by $2, although most merchants charge $49 or more. (For further comparison, we saw Office 365 for free for teachers and students last month.) It includes Microsoft Word, Excel, PowerPoint, OneNote, Outlook, and OneDrive cloud storage. Deal ends April 1.
