When I log in as a member of the group prices display correctly on the product page. Prices are also correct when I add a quantity of 1 to my cart. However, when I increase the quantity in the cart, the calculated item total is wrong, it's always a penny less than what the correct total should be. I assume, it would multiply the quantity by the price but apparently it doesn't. Has anyone experienced this same problem or have any idea as to what may be going on here. The difference is only a penny but it's creating havoc for our Customer Service folks.
A quantity of one calculates fine:

Increase the quantity and the calculation is off by a penny.
