Hi,
I want to set discount for customer buying from 5 pieces or more of product in the same category.
Every products in that category has the same price.

Could anyone show me the picture for that?
Thank you very much in advance.

Hi,
The solution will be to :
- Create a "coupon"
- Use the Minimum number of products restriction and set it to 5
- Set the Auto load in cart if possible option (commercial editions of HikaShop), to YES, then your coupon will automatically be added to your cart when it's possible.

Thank you very much. I got it already.
