Mountable Ruby-on-Rails E-Commerce solution.
Piggybak is a Ruby-on-Rails 3 Engine with basic shopping cart and one page checkout functionality.
It uses Rails Admin to provide an admin interface to work with orders, products, shipping methods, payment methods, and tax methods. It is not an ecommerce turn-key solution, but is intended to be mounted on existing Rails applications.
Piggybak is open-source and free to use.
