Southland Organics
Southland Organics sells animal probiotics, horticulture and bioremediation products. The new Drupal Commerce version was ported over from an Ubercart site in order to take advantage of entities, "option images" and flexibility with views and the checkout process.
Additionally the site was put together by reverse engineering Commerce Kickstart and uses no customizations not available to the community.
The site was built by http://prolifikseo.com with gratitude to Commerce Guys.
