How to apply 10% discount on grand total price on cart page Magento?

Question

I am using Magento 1.9.0.1. I want to give 10 % discount on grand total price in cart page for specific users and will show in cart page, order review page and in admin panel as well.

I follow the apply discount coupon thoroughly but unable to do that. I searched in Google but didn't fill my requirement.

Answer 1

You can use Magento coupon only.

Just login to the admin panel
1) Promotions->Shopping Cart Price Rules
2) Add New
3) Actions
4) Apply -> Percent of product price discount

Its done.
