They always do that, and even with the great discounts is more expensive than other stores. The CC around here close in January and on the last day the had 70-90% off, I gave $ to a guy working there and he hid a brand new samsung lcd 1080p 120mhz 52" and 2 GPS devices. I got the TV at 70% off for $500 and the GPS at 90% off for $50 each. The manager was furious, he was asking where did I found those because they were looking for them the day before.
The last 3 days is when you can get real deals and I don't mind go through the manufacturer for the warranty, you can actually contact them and even buy an extended one. I had samsung replace a TV before with no problems.
