Hello all. I'm using the built in quantity discounts feature of Zencart. For some reason, I'm having issues though with the discount calculation.
example. I have a product that goes from 18.50 to 18.00 when you buy 6 or more.
If I purchase 3 of one attribute set, it sets the 3 at 18.50 each (correct).
If I then purchase 3 more of another attribute set (color, size), then those 3 are correctly priced at 18.00 each, but the previous 3 remain at 18.50 each (incorrect).
If, on the other hand, I purchase 6 of one attribute set, then the cost is correctly calculated at 18.00 each.
Using zencart 1.3.6.
Any advice would be appreciated.
