Disable the coupon field for certain products?

-- HikaShop version -- : 2.3.0
-- Joomla version -- : 2.5.19

Some of my products has coupons and some don't need coupon. I want disable the coupon field for certain products. How can I do?

Hi,

There is no such option in the coupon. You just have an inclusion system.
So the best is to create a category and put every products, except the products that you want to exclude.

Regards,
