Best Buy offers the Person of Interest: The Complete Third Season Blu-Ray / DVD Combo Pack for $14.99. Choose in-store pickup to avoid the $2.99 shipping fee. (Amazon charges the same with free shipping for its Prime members.) That's the lowest price we could find by $29 and the best deal we've seen for the third season on Blu-ray. This 10-disc set also includes a digital HD UltraViolet copy.
