VirtueMart is a complete Open Source E-Commerce (Shopping Cart) solution with a lot of features. It's a Plugin for the famous Content Management System Joomla! (also: Mambo). Joomla! and VirtueMart are written in PHP and made for easy use in a PHP/MySQL environment. Joomla! provides the Core System and the Framework, which Virtuemart can use. So you can easily use a complete Shopping Cart Solution within your own dynamic Website ("Portal"), together with many other Plug-Ins, called Components and Modules, like a Forum, FAQ, Guestbook, Gallery and so on. You can change the look and feel of your site quickly using templates. Even if you think that you don't need a Portal or a "big" CMS - think about and just try it! You are more flexible.
