I am trying to apply coupons to a specific product attribute. However, the pricing service only checks discounts via the product which does not give me access to the product attribute. Is there a way when the product is added to the cart I can temporarily add the attribute sku to find the discount?
For example I have a product with sku bno1 and then two possible attributes bno1a and bno1c. I need to be able to have a coupon code work with one of those two skus.
