They have some products that use the coupon facility, where 10% is deducted. What they have found is that 10% is being deducted from the original price and the VAT worked out is based on the new price, but the final total is derived from the original VAT cost and not the deducted cost. Here's the calculation (I have also screenshot it as well as setttings in backend). Cost of product = £35 10% deduction = £3.50 £35 - £3.50 = £31.50 20% VAT on reduced price = £6.30 (this is shown in checkout) Final charge should be = £37.80 Customer charge = £38.50 We think this is because the VAT on the original £35 is £7 So the £38.50 is calculated by: £35 - £3.50 + £7.00 = £38.50 They have had this problem for awhile, just not got round to sorting it. Can you advise on what the issue is. Any help greatly appreciated.

Then, in the HikaShop configuration, you can change the "Apply coupons" setting in the HikaShop configuration.
