Hi Logos - there's a pricing bug from the MM website and the checkout logos.com page. The items for D. A. Carson on the MM website does not match the items at the Logos checkout when you select "Buy All" call to action. In addition, the pricing for The New Bible Commentary is not applying the discount of 75%. It still shows $45 even when singly selected and coupon applied.

Figure 3 is a cross comparison of items and the pricing with a note on the side indicating if there is an issue or not.
