django-oscar is a ecommerce framework for Django 1.3 for building domain-driven ecommerce sites. It is structured in way that lets any part of the core ecommerce functionality be customised to suit the needs of your project.
It is currently in vigorous early development, but should stabilise over the summer of 2011.
