This is the session video for my DrupalCon Chicago presentation, Drupal Commerce: Setting up shop on Drupal 7. The video includes a presentation of the overarching vision and architecture of Drupal Commerce followed by a technical demonstration using the Commerce Guys demo store.
As of DrupalCon Chicago, Drupal Commerce should be considered stable and ready for developers and advanced site builders. We're in solid beta territory and are fixing bugs in preparation for a final 1.0 release. The main limiting factor is the availability and stability of contributed modules.
