The product catalogue allows you to arrange your products in categories and subcategories. You can create new product categories and add products under each category.
The shopping cart allows customers to easily select and pay for multiple products on your website.
Content Management Systems
The content management system allows you to manage the content on the non-catalogue pages of your store (i.e. shipping and returns, contact page, terms of service, etc.).
This feature allows you to have different product options (i.e. size, colour, etc.). You can manage these options and assign them to particular products to create a wide variety of products.
This allows you to have different shipping methods for your store and to define shipping zones (e.g. countries and regions) for each method.
