Just a few suggestions,
do some comparisons at Google's Shopping service:
Google Product Search
What I like to do is go to a store and locate a part nuimber and pricing of a particular item, in your instance,
HDTV, and then go to Google's price comparison service and see which offers the cheapest pricing.
Now, my favorite service is
NexTag - Compare Prices Before You Buy for finding a charted history of pricing on particular products. Here's a chart of a Samsung LNT5271F 52"
LCD HDTV for example:
Samsung LN-T5271F 52" LCD TV: Compare Prices, View Price History and Read Reviews at NexTag You can see where the price dipped around the winter holidays, but it's steadily increased in price since then.
Good luck and do your research, it'll save a lot of money.
