If you are looking for something that has the basics down (cart, product details, customizable payment system), Cartridge and Mezzanine are the way to go IMO
Its one of the best Django solutions I've come across.
I've worked with other bigger bloated eCommerce solutions - Magento, Opencart, Zencart. But LFS is seriously fast. Clean, well written code and stable.
I'm also using LFS here[1] for a furniture shop.

Mezzanine (and Cartridge) really go a long way in providing an enhanced version of Django's admin that's suited to handing over to clients, so your third-party apps plug straight in.
Mezzanine provides all the basic features you would need in a CMS and then makes it very easy to add anything custom or unusual you might want. In this way you don't get overwhelmed by stuff you don't need.
