The last time I was buying, a guy at the North Shore Automall wasn't even going to tell me his "best price" until I "committed" by making a down payment. I said was that wasn't going to happen until I knew the price, and he basically shrugged and said "have a nice day".
Same thing happened to me last fall at Richmond Auto Mall. Took a vehicle for a test drive, back to the dealership and told the salesman I wanted to talk numbers. They said they wouldn't unless I was "committed" to buy. I did a WTF look, got up and left.
How do I know unless I know the price?
