Hello,
This is my first post:
"Purchase and activate a qualifying Office 2007 product between March 5, 2010, and September 30, 2010, and you can download Office 2010 at no additional cost."

This is a great deal for students since the Ultimate Steal deal still has Microsoft Office Ultimate 2007 for $59.95 + $13.00 for a backup DVD ($72.95 total).
