Is anyone else having trouble with tax calculation when using promotional codes?
The attached image shows the problem I am having and my tax settings.
Basically, I am asking for the discount to be applied after the tax - so the Subtotal should be Â£10 (after discount applied).
Then the shipping added on (making it Â£13).
Then the tax total should be 20% of this (Â£13 x 20% = Â£2.60)
