Very clear as to what corner is positive and negative(the bars even show it). Click this link and check the pics by clicking on any of them. You see the orange end of each cell is negative. Hope this clears everything up for you.
As for your second questions you would really need to call and ask Erika she does all the pricing and web updates. It is possibly a typo....but you never know.
