Sooperthemes.com has just been migrated from Ubercart to Drupal Commerce. If you experience any problems please let me know at the contact form.
This Migration marks the start of a number of updates that will together mark the 4th major version of Sooperthemes.com. The site has come a long way from version 5.1 (on alldrupalthemes.com) and will soon feature a responsive design, improved shopping experience and more community features.
