Does anyone know the name of this ecommerce environment?

Hello,
a little while back, I ran across an free ecommerce storefront that I believe was in php. But i forgot where i saw it or what the developer's url was.

All i remember is that it was very minimalistic looking with a bare bones shopping cart etc. It looked very modern and easy to set up.

Here is a site which i believe uses this software:

Can anyone tell me what environment this is, or tell me of a similar free, minimal ecommmerce storefront like it?

thank you

 

It's osCommerce or one of many derivatives.

 

Thanks for the help...
does anyone know the simplest and most minimal looking variant/derivative of osCommerce?
