When a customer ordered on the website they had the 15% discount for the 3 cables, then the customer called and said he ordered 3 cables by mistake and just needed 2, so asked me to amend the order which I did, normally the system amends the price accordingly, but since it was bought on the website with the discount, the discount is locked and we can't amend it. So James said in the future if that happens again we will need to cancel the order and ask the customer to place a new order with the correct amount of cables to reflect the correct discount
