Appendix D. E-commerce
If you want to sell something on the web, Drupal may be the platform for you. If you are selling tangible goods (like books), virtual goods (like downloadable music), event registrations, or subscriptions that allow visitors to view pages on your site, then Drupal and either Ubercart or the e-Commerce contributed modules are a perfect combination. Get your cash register ready: at the end of this appendix you'll have the information necessary to sell items on your Drupal site.
Ubercart has not been ported to Drupal 7 yet, but is expected to be available soon after Drupal 7 is released. This appendix was written using the Drupal 6 version of Ubercart. There may be differences in the Drupal 7 version.
