When we choose to shop a product online through a web site, we are facilitated with the list of product by that site.  To choose that particular product we just has to click to that appropriate link. As we click to the link we are transported to the next page where we have to enter our credit card number or related information. The process starts with filling up the form by the customer with necessary information like address, phone number and other credentials. Once he finishes the initial process he is only away with one click at “submit order” button to validate his purchase.
