Helps on implementing a simple shopping cart site with Drupal commerce
I am new to Drupal commerce and I have some basic understanding on Drupal7 (know how to use CCK etc but not development yet)
Now I am going to implement a simple shopping cart site with Drupal commerce
1. Are there any fully functional shopping cart site with theme (beside the installation profile) available for download?
2. Should I implement my site with a module or just a theme? (If I don't need extra functionalities)
