Broadstreet has developed expertise in Drupal, Broadstreet's primary approach for building eCommerce solutions. Drupal is an open-source (free) content management system along with Ubercart, an open-source shopping cart solution. A Drupal/Ubercart solution will allow for much more flexibility, the ability to easily add a blog, a calendar, a discussion board, or numerous other features to your site. This type of site will take a little more effort to build and will be a little more costly to maintain.
