I have created a cart price rule which contains specfic coupon and percentage of product price discount(10%).
How to checkflow of Magento apply these rule.
First check on which websites, which customers group you used in that rule. then check conditions and actions for your rule.
After that, you add the product to the cart and check
checkout/cart page. If cart price rule is applying for this product that you can see discount is applied to the product and you see in a summary also.
Please see below screenshot, I create one cart rule and it is applied to a product when product price greater than 100 and I applied 10$ fixed amount discount.
In your case, after adding the product to cart, you add coupon code in
checkout/cart page. After adding this code your rule work and see a discount label in summary also.
I hope this will help you.
