The price shown on the sony website is often the price it was when it was first released, but over time the price drops. I think there has been a recent price drop on Sony LED TVs. Also noticed the same thing with canon digital cameras where their normal price (not an advertised special) has dropped.
For example the 40 inch led sony KDL40EX520 on the NL website is $1299, and also $1299 on the bond and bond website (both operated by the same company), yet neither say that is a 'special price' or what they have been reduced from anything.

JB Hifi has their price of $1284, undercutting it. Price spy shows that most retailers are selling it for around the $1200 -$1300 range, so I think that is around the current normal price. However last weekend, the bond and bond website had the same TV advertised on special for $1099 reduced from the normal price which I think said $1299 was the regular price. So it doesn't appear NL has taken 20% off it for some reason.
Even if it was 20% off sonys RRP of $1599, that should make it $1279.
Maybe Sony complained about their higher end TV's value being castled?
No wait... that doesn't sound right...

Noel Leeming were advertising a 50" LP HD ready plasma for $799 on their website yesterday, but today it was gone. Not like I'd ever consider an HD ready 50" TV... but I'm sure many people won't worry about picture quality, and will like to have a cheap tellie that helps them 'keep up with the Jones's'.
