Microsoft is having a Black Friday sale. Go figure.

The Redmond software giant is cutting the price of Office for Mac 2011 starting Thanksgiving Day, and continuing through Monday November 29. The depth of the cuts may vary depending on the vendor, but Amazon is reducing the Home & Student Edition (which does not include the Outlook email client) to $80 for the single-license version and $110 for the three-license pack. Regular Amazon prices are currently $120 and $150 respectively. The Apple Store, Best Buy and others will also cut prices, though it's unclear how deep their discounts will be.
