Newegg has Microsoft Office 2010 Home & Student (3 licenses) for $100 with free shipping. Includes Word, Excel, PowerPoint, and OneNote 2010. It is licensed for installation on three PCs in the same household. Microsoft also offers Microsoft Office Professional Academic for $100 for qualified students.
Cant beat this at $33.33 an install.
Best deal I have ever seen on the 3 user pack.
How are the student/academic versions different from retail box?
