If you haven't yet gone high definition, or even if you have, Amazon is offering a week of high def deals, with amazing savings on HDTVs, Blu-ray Disc players and movies, speakers, home theater receivers and accessories for your home theater system. These deals are available in two forms: Lightning deals, which last up to four hours (depending on stock) and Gold Box Deals, which last a full day (again, depending on stock).  There's even a home theater "deal of the week," which is a $400 Velodyne powered subwoofer on sale for $189.99 including shipping (that's 52% below list!). 

Today's Lightning deals include a high-end Logitech Harmony 890 remote control for $120 (60% below list), and a Sylvania Blu-ray player for $129.99 (35% below list). Today's Gold Box deal includes multiple products with savings of 50% or more on Definitive Technology Speakers and 33% off on an HDMI-switching home theater receiver from Denon. 

Update: Deal of the Day for Thursday, June 11th is a PS3 (PlayStation 3) for $349.99 delivered!

So keep an eye on Amazon this week for some killer deals on all things high definition, both video and audio.
