Read the first half of the page so not sure if it has been mentioned, but fuck yes I do.
At best buy / etc they are given a limit which they can knock down an item. Best buy is the BEST place to haggle because their service is fucking horrible. I fart around for an hour act like I'm pissed and go get the manager and they knock off huge amounts of money. I saved $150 on my monitor (which was a 3ed of the price..) because of this. I was acting like I was angry that no one was helping me, had cash IN MY HAND, and said I wanted a screen. When he told me the price I turned to walk out and hes like "wait wait, how about $150 off, the same as the the model next to it[ a 19' screen

]) Current screen = 25 inches and pure awesome. He threw in free hdmi cables and a wall mount on top of that.
Post ramble: You're fucking retarded not to haggle, they want your sale.
