Looks like The Good Guys have beaten JB hi-fi's "wicked Wednesday" price on the Panasonic 55" TV (TH-L55ET5A) by $1. They also have a promotion running where you receive $50 store credit for TVs over $750 if you buy online and pick up in store.
I doubt they would budge much from this price if you tried to bargain in store anyway, and the price seems to have been well received by quite a few people.

edit: looks like this price was only applicable during the same hours as JB's wicked Wednesday sale. Price has gone back up :(
Also beat jbhifi by $1 on the samsung 51 inch 3D Plasma http://www.thegoodguys.com.au/buyonline/Samsung_51%22_130cm_…
