Don't know much about rails but for Django there - Satchmo(http://satchmoproject.com/ http://satchmoproject.com/) - Lightening Fast Shop (http://www.getlfs.com/ http://www.getlfs.com/) More info - http://djangopackages.com/grids/g/ecommerce/ http://djangopackages.com/grids/g/ecommerce/ - http://readncode.com/blog/the-state-of-ecommerce-in-django/ http://readncode.com/blog/the-state-of-ecommerce-in-django/ I used Satchmo sometime back and it's a very good but low level solution. You can do a lot with it. I did not use LFS but it seems something which can help you setup a cart very quickly, like pinax does for social sites. EDIT: Fully agree about Magento/WP. From a cursory look into Magento internals seemed of questionable design and unnecessarily complicated.
