The Puji store was migrated from Zen Cart and uses Drupal 5 and Ubercart 1.6

The site uses the panels2 module for both product pages and category listings, so we created some panel panes to provide the grid layouts and category navigation (to replace the Catalog module.)

We customised the product pages extensively to allow a product to contain multiple size variations and to show stock / lead time for each.

Thickbox module was used for the larger product images.
