Hide coupon

-- url of the page with the problem -- :
-- HikaShop version -- : 2.1.2
-- Joomla version -- : 2.5.9
-- PHP version -- : 5.3.3.-7

How can I disable or hide the question "Enter your coupon" in the check-out workflow?
I don't want to use or show it.
Can't find a parameter to disable it.

Hi,
You'll just have to :
- Go to "Hikashop->System->Configurtion->Checkout"
- Set the "Advanced checkout workflow edition" option to YES
- Remove Coupon from the checkout workflow
