Could it be a "black-and-blue" Friday for Blu-ray? K-Mart has already decided not to sell Blu-ray players at all because of the affordability chasm between the two. The cheapest Blu-ray player at Wal-Mart runs $464. The Xbox 360's external HD-DVD drive is now available at $179, and that comes with five free movies. Consumers can get even more free titles with their purchase at Best Buy.
