In other words the very window (The $189.00 window) they advertize, is not the one they try to sell them once they get (your foot caught in their trap) their foot in your door. This is a form of bait and switch sells tactic.
Of course if you stand your ground and "demand" to be sold a $189.00 energy hog window! They by law are obligated to sell you as many $189.00 energy hog windows that you want!
You may want to ask yourself before doing this though! "How bad do my old energy hog windows look? Because all you may gain is a cosmetic makeover of your old window sashes.
