A few months ago, Amazon was giving away an Xbox 360 and HD DVD add-on drive each day along with a box set of Heroes. Right now, they’re giving away an HD DVD player each day, along with 100 HD DVD movies. The contest started January 14 and ends on February 12. You enter once and are eligible for the whole month, so if you don’t get picked for a particular day, you’re still eligible for the other days of the month.

They’ll be drawing the winners randomly on January 21, January 28, February 4, and February 18.

Amazon has the same contest going on for Blu-ray as well, with the same dates and terms.
