Using a content management system like Drupal means that maintaining a website is a breeze. If you know how to edit a document using Microsoft Word, you can create and update your own content.
Drupal also makes it easy to integrate PayPal into your ecommerce site, or to add hundreds of other features easily! This makes for a smooth and sophisticated website [and takes your designer less time than hand-coding it from scratch! That means you save lots of money!]
