Hi,
Every HikaShop products can be in several categories in the same time. A product option is basically, an HikaShop product.
I am saying that in order to apply a coupon on several products, the best is to put these products in a same category and apply the coupon on this category.
I am saying that a category which is not published, won't be displayed in the front-end.
I am saying that a unpublished category is useful if you want to apply a discount on several products in the same time.
It is not possible to create several coupons with the same code.
And because you can't select several categories but just one. The "trick" is to have one special category which will regroup all targeted products.
Because a product can have several categories, there is no specific problem. You just have to add the special "discount coupon category" to the products.
Is it more clear ?
