I should have done more reshearch before I asked the question online. I fired up CS web site which they call "price". I then compared CS to TOS, price vs mark. They seemed to be the same.
I then click on the information box on CS for price and got this pop up. It seems to be right for both web sites. Not to hard to find for a very short time where price or mark is outside the B/A.
