If you are buying or selling, understanding the market price for what you've got will let you know if you're making the right deal or not. Job offer negotiations sort of suck in this regard because you often don't know the market price, and if you set your number too low in your head, you're pretty much stuck starting off lower than you should and that can impact your entire career. You might think you're doing good negotiating, but the guy next to you might be making 10-25k more a year just because they started at a higher number. It's weird but true. Same applies to buying or selling just about anything. Have as much data going in as you can about what is normal, fair, etc. and compare that to what you want.
