Übercart is a complete, Drupal e-commerce solution. Check out the Übercart project page at Drupal.org. The developers of this fine looking piece of e-commerce goodness call it an escape from osCommerce. (Is it also an escape from Zen Cart – the previous osCommerce exit strategy?) The best news is that it is a collection of Drupal based modules – not a hack in – that will allow other great development options for an e-commerce website:
Content development
Several great options for ratings and reviews
Discussion forum
Community development
Flexible theming possibilities
The list goes on…
