Hello. i am running zen-cart 1.3.9h. everything is fine besides this:
when i make 10 or 20 or 30 % discounts via sale maker , the sub-total calculation in invoice goes off. here is the invoice example of items discounted for 30% off:
Total (inc)
17.47
33.54
5.60
8.37
-----------------
sub total 64.96

then it should be 64.98.

anyone knows how to fix this?
thanks!
