royalgems.co.nz was originally made with zencart many years ago, however the customer was not happy with the functionality and the site looked rather ugly. I ported this site to Ubercart/Drupal and made a number of improvements along the way.
Features of this site:
* Full e-commerce solution including catalogue, product variations, stock levels, payment gateway integration, discounts, tax, invoices, cart, etc.
* Mailing lists
* Custom built payment gateway for paymate.co.nz
* Custom theme
* Product preview image popup
