Logos should explicitly state what gets charged to the customer's account in the Order History and Order Summary screens. It did explicitly say $170.62 in my cart (what got charged to my account). But, immediately after hitting the button to purchase, I saw $261.61 as the total order everywhere and got pretty nervous. I followed up with a representative, who patiently explained it to me, but I suspect making this more explicit will save Logos from having to field a bunch of unnecessary calls in the future.
