The answer is yes and it gets better.
I ordered my GT in November last year. When I placed the order we settled on a price that was TrueCar good. I asked for a little more but the Sales Manager declined saying we locked in the deal and it wouldn't move higher but it was likely there would be more discounts announced before the car was delivered and I would get to take advantage of those. So I went ahead and ordered.
Fast forward to the car being built and in shipment to the dealer. I was browsing the dealers website looking at the cars they had on the lot and the cars they were waiting for. This dealer has all its cars automatically added to their website and they put discount pricing on all of them. So imagine my surprise when I see my car (with vin in the ad) listed as available for a lower price than I had locked in at order time.
I printed the webpage and took it with me when the car came in. I had already arranged my own financing so the delivery process was really simple they appraised my trade and started filling in the amounts owed and then I produced the printout and told them the price had changed. The Salesman was puzzled, not clear on what to do he called the Sales Manager over and in the short conversation he confirmed they had to honor the price on the website. The result was I got even more off the price and was a very happy new owner when I drove home. It pays to pay attention to whats going on. Good Luck. And You're Welcome.
