Ask HN: How do I create a copy of this website?

Finding the exact template is always quite hard, best is to find the closest looking template and edit the CSS accordingly. Here's the closest match I found : http://goo.gl/NlmtDH

is it possible to clone a websites template?

Prestashop is self hosted. Check out the demo [1].

There are other solutions too - Magento, WP-eCommerce...

You probably won't find a theme that's exactly the same. You should look at themes that have functionality you would like to use (sliders etc) & just style it yourself if possible.
