Hello I can't find anywhere how to make promotion ... or module that can show some product on SALE
like 3 different product that are on sale or promotion ....
I tried hikashop content module but it doesn't give me options to put 3 different product on promotion...

How can I do this ?
Is hikashop has options for promotions or product that are on SALE (20% off) or something like this ...
I am using RocketTheme and RocketTheme module right now but only thing that I can do is put articles.. Is there any way to connect this if hikashop doesn't have something similar ?

Thankyou for your support ...

Hi,

To add discounts to products you can do that via the menu Orders > Discounts.
The discounts can be applied on categories, so create a specific category for that, apply the discount on it, then add the products to this category too.

Finally create a content module and use the "discount category" as parent category. This way in the module only the products with discounts will be displayed.
