From Open Source Initiative (OSI):
"...The basic idea behind open source is very simple: When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing..."

From the official osCommerce website:

osCommerce is the leading Open Source online shop ecommerce solution that is available for free under the GNU General Public License. It features a rich set of out-of-the-box online shopping cart functionality that allows store owners to setup, run, and maintain their online stores with minimum effort and with no costs, license fees, or limitations involved.

The goal of the osCommerce project is to continually evolve by attracting a community that supports the ongoing development of the project at its core level and extensively through contributions to provide additional functionality to the already existing rich feature set.

Everything you need to get started in selling physical and digital goods over the internet, from the Catalog frontend that is presented to your customers, to the Administration Tool backend that completely handles your products, customers, orders, and online store data.
