Dear,
When I enter a coupon code, the TAX is still calculated by the price without discount.
exam
Price€ 1663.20 EUR
Tax € 99.79 EUR
Discount € 352.60 EUR
Total€ 1410.39 EUR
Direct pay € 1410.39 EUR
6% tax, 6% of 1663.20 = 99.79
But the TAX should be from the 1410.39, because over discount you can't pay tax
