i have integrated the Quantity Price Break for SPPC([url removed, login to view]) to my web site. Everything fine except two bugs at the shopping cart when I log in the wholeseller group. (a) subtotal not reflect the quantity price (b) credit point only reflect the original price. It is likely that there is a bug at the include/class/shopping_cart.php. The module work well at retailer group.

bug related to (a) has been resolved.
