Commerce Kickstart is the fastest way to get up and running with Drupal Commerce, the e-commerce framework built from the ground up for Drupal 7. Commerce Kickstart installs the latest versions of Drupal 7, Drupal Commerce, and the other modules required by Drupal Commerce.
The distribution adds one step to the installation process where you can choose to create various types of example store content. The types of content currently supported pertain to displaying products for sale, but ideas for expanding this support are welcome.
