LiteCommerce 3 is a free, open source (OSL 3.0) PHP-based platform for fast and easy creation of e-commerce websites.

It can operate as a stand-alone solution or like an e-commerce module for Drupal 7. When running it in a connection with Drupal 7, you get tons of free content management functions, themes and modules from the Drupal community, which you can use for faster website development.

LiteCommerce 3 has a clean and smooth user interface with cool Ajax enhancements like one-page checkout, quick product view and dragging products to cart with the mouse.

Another great feature is the ability to install LiteCommerce upgrades and add-ons (made by the LC3 team or third-party developers) directly from the shop's back-end.
