Catalog price rules enable you to set price reductions by category, brand, supplier, feature, or attribute. As the name suggests, these types of rules apply to a wide range of products. It cannot be used for a single product.
For example, you can set a rule to say that for Iranian customers belonging to the "good customers" group, a 5% discount on all Sony products will be implemented for the first week of August.
