I have the same problem & no it doesn't matter whether there is a discount or not:


Sub-Total: $359.98


Table Rate (15.00lbs) (Best Way): $25.00


5.0% GST#85990 7784 RT 0001: $7.50


8.0% PST (Ontario): $12.00


5.0% GST on shipping: $1.25


8.0% PST (shipping): $2.00


Grand Total $435.03

GRAND TOTAL IS LISTED AS $435.03 but adds up to $407.73....
GST should be $17.99 or $18.00
PST should be $28.79 or $28.80

GRAND TOTAL NUMBER IS CORRECT, BUT THE GST & PST NUMBERS SHOWN ARE INCORRECT. IT IS CALCULATING IT PROPERLY IT'S JUST NOT SHOWING IT PROPERLY.

SHIPPING GST & PST IS CALCULATED CORRECTLY!!
