Just checked the reference eCommerce website- Cellairis; as per observation, it is built with Asp.Net MVC 4.0; Bootstrap CDN, OSS CDN, Zencoder CDN is used over there. VideoJS html player is used also.
◘ As this is an eCommerce system so an intuitive search module at the very first page of the website be beneficial. User can make search by product category wise, Price range wise etc and with various other attributes.
◘ All the main category of products should be as sub menu under the product menu. Even can remove the product menu and replace all the main category of products like iPhone, iPad etc as main menu.
Those 2 points helps customer to find out easily their required product. It will make your website more popular and user friendly than Cellairis.
The flow is like:- User search for products -> all available product be visible -> on click of any particular product, all details about the product be visible -> Add to cart button be available and with mention the quantity of the product -> After that User will provide shipping address and Payment Module.
