Right now I am working on Magento2 Promotion functionality.as per our client requirement we need to apply a discount on the product based on quantity(using the catalog price rule).
For that, I have reviewed the Magento features, But in default Magento, there are no options for setting the discount based on product quantity in catalog price rule.
the promotional condition is, the product should have the particular attribute also follow the below cases to apply the discount.
if the product quantity has 2+, the discount is 10% (which means the quantity > 2 or <=6 )
if the product quantity has 6+, the discount is 20% (which means the quantity > 6 or <=11 )
if the product quantity has 11+, the discount is 30%(which means the quantity >11)
Weather do you have any code level idea or third-party module for accomplishing this functionality means to share with us.
