It's an option that comes up after the dealer submits a response to your "Request a Quote". Nissan put it in there because they assumed that there would be some "back and forth" between customer and dealer before the customer finally accepted a price. In reality, that's not how it works. Half the time, you're lucky to even get to the step that your at -- many dealers just ignore your RAQ if they haven't already worked something out with you in person or on the phone. In addition, if you actually did try that button to get a better price from the dealer, the odds of that happening are slim to none -- 99% of the dealers aren't negotiating on this car. As someone else said, it's best to get a firm deal worked out in person, on the phone, or via email, and then submit an RAQ to that dealer. It's unfortunate, because Nissan went through the trouble of building this nice car buying system, and no one wants to play along and use it!
