There have been a lot of conversations about the evolution of Ecommerce support on the platform. This wiki section will capture the messy details and evolve as we converge on an approach.
At a very high-level, there is some important context:
The Django Oscar based Ecommerce service has been deprecated and is unmaintained
We have developed a simple integration with WooCommerce as the reference implementation for a different approach. This approach recommends that the Open edX project does not have a customized commerce service, but a robust set of APIs for integrating with best-of-breed solutions.
There are existing users of the Django Oscar Ecommerce service. The plan should support those users migrating to something better.
