Hi

My role discount is being applied to the order subtotal correctly, but then my GST is being calculated against the original order subtotal, not the discounted subtotal.

So for a 20% discount and 10% GST I get:

Subtotal: $100
Discount: $20
Subtotal $80
GST: $10 (Should be $8)
Total: $90 (Should be $88)

Anyone with a fix?

Thanks

Glenn
