Buy.com offers the McAfee AntiVirus Plus 2011 3-User for Windows, model no. MTP11EMB3RAA, for $13.25 with free shipping. That's the lowest total price we could find by $12, although we saw it for $3 less last month (since expired.) It includes protection against spyware, viruses, and phishing, a 2-way firewall, and more.
