Not at most national places.
More up to the MGMT, who is in control of the pricing.
Prices are not a result of the evil tv sales man...(LOL)
Some places like CC (paid 2.8%), taking $200-300 off the price only effects the salesman's commision less than 10 Dollars, and is far better than not making the sale.
Most stores and managment have strict pricing policies in place, and very, very few actually are allowed or supposed to negotiate prices.
Thus the "pricematch" results... Basically in order to get a good price you have to give them an excuse to give it to you, cause if a CC or sears or Best Buy guys (manager or sales guy) was caught negotiating price without reason they would be canned quickly. Keep that in mind, it good to know when seeking the best price. Some places just can't give you a great deal, you need to help them give it to you with a reason.
Margin is also getting lower and lower. Somtimes a better price can not be had. With these lower end models comming out at reduced MSRP's to be more price attractive (basically every model under $2500 ) there is less margin than there used to be on it in the past. If a $2500 is on sale for $2199 plus free delivery, set up, free dvd player and 12 months no interest, there is not that much more discount to be had it the cost is near the $1800 since after all is said and done, (shipping, overhead ect.. )they are making little money on the deal as it is. It is not reasonable to expect a discount on every bigscreen tv purchase, espeacially if you catch a good sale at the time. If it is full price, I would atleast expect the sales price though....
