Jennie:
My experience with dealers is probably not as extensive as that of the many who will no doubt respond, but I've bought a few pieces, and this is how it went: one dealer dropped 15% off his price once I hit his "magic number". Prior to that it was 5% to 10% off his posted prices (which were list or just a bit below). On certain items, he'll do me even better now, but on low margin items it's list or walk. I worked with this guy for several months, built a rapport, and still visit just to keep in touch or listen to whats new. Another dealer fought like a wildman over every penny, no discounts and no help, until I found something he wanted off the floor - 20% off immediately, and then my wife turned on the blues - another 10% later I was one happy audiophile (he even gave us new in box instead of floor models - cool dude!). Another dealer is pretty straightforward - his price is 10% off list, specials as marked, doesn't care a fig to haggle. I respect that approach, but have yet to buy anything there. If there is a rule of thumb in there, I dunno what it is, except perhaps to try to find a dealer you like, take some time with them so you both know what you want and what you want to spend, then see what kind of a deal you can make.
Good Luck!
