From my experience as a fairly frequent HDTV purchaser over the last 5 years (two 55” LCD’s, one 60” LED, and two DLP projectors) the best deals are almost always between Thanksgiving week and Christmas Eve

Well here I am, for the first time in my life, at a bargain time.
Usually the prices are raised when I walk through the doors. I can be seen from miles away, and customer service reps cry out to each other: here comes the only human on earth who has to pay Manufacturer’s Suggested Retail Price!!
My strategy has always been to scope out a superior model (one that you've seen in person and like the picture of, which has been available from the manufacturer for a good while which has other benefits) and get that model on a closeout deal when a new model comes out.
If you have a Sony outlet store close to you, they will offer those deals before anyone else, which is where I bought 2 of my HDTV’s that I feel were the best 2 deals overall. The 60” LED was $800 below Best Buy’s on sale price, was brand new (they also have refurbs) and the extended warranty was less than half BB’s cost as well.
If you want even better comments from people on these subjects, check out avsforum.com where I learned the ropes myself, but no pricing discussion is allowed. Good luck finding the set you want, and always go bigger because it wont look near as big after a year or so.
