This is a single item e-commerce site that I developed. The product is an oil for dry penis. When they hired me the site already existed and I only made minor changes. A couple months later they asked me to rebuild the entire site from scratch because they wanted it to be responsive and they needed to use the new version of the PayPal API. The only requirement for the rebuild was that the database structure remain the same so that their existing analytics package would continue to work without modification.
