Last month Cutler & Gross asked us to help them with their new e-commerce site. They had chosen Prestashop for their platform and we were bought into to fix a rough installation. Initially we focused on tightening up the front end design to fit with their main site and adapting the site to look as good on a mobile as it does on the desktop.
This was a our first major install using Prestashop and it seems to have some nice features out of the box. The store is configured to use an alternative price list for the US and Canada and displays the dollar currency based on the visitors IP address.
