Magento: How to remove discount coupon code?

You can post discount codes in emails, blogs and social networks to generate more traffic and entice paying customers to your ecommerce website.

Fortunately for ecommerce web designers, it is quite easy to disable the discount coupon code function on a Magento shopping cart website.
