Discount on a category does not work correctly.

If I want to give 15% discount on products in a category, and I only buy products from this category
I get assigned the correct discount.

BUT if I choose a products from a category where I do not give discount + buy a product from the category where I want to give discount module provides 15% discount on both products.

So discount on a category does not work correctly.

This depends on the behavior you select when creating the coupon.

If you set the discount type to "Specific", then it will take the discount on just the products in the category.
If you set the discount type to "Overall", then it will take the discount on the overall cart of products.

This gives you better control and more options.

Thank you Seyi!
