This Drupal Commerce instance featured several advanced features such as custom shipping rules, digital downloads, inventory-accurate combo packs, discounts, coupons, affiliate marketing tracking pixels, product reviews, pre-ordering, and integration with FedEx via Shipstation. Payment gateways included Paypal, Authorize.net and Amazon LPA. Digital Downloads were fulfilled by VHX via integration with their API.
The next evolution of the e-store at Cesar's Way, was a migration to the Shopify platform. The transition was straight-forward yet required diligence and creativity to replicate the necessary functionality and features from the Drupal Commerce site. Digital downloads were achieved through Sky Pilot. Custom shipping rules were made possible by the Advance Shipping Rules app. Fulfillment by Shopify was maintained as well as all other needed functionality from the previous store.
Dog's Best Collection is a good example of one of my WooCommerce creations. The store sells many products with several size/color/flavor variations which had to be configured. The client also needed the ability to offer home delivery within 30 miles of his warehouse.
This was the original Cesar's Way e-store built in Übercart. I was the administrator on the store for 2 years and made a number of improvements and integrations to it during that time. I migrated it over to Drupal Commerce when I upgraded Cesarsway.com from Drupal 6 to Drupal 7.
