Sales refer to the practice of selling products or services through one or more of many different mediums in return for money or some form of compensation. Some of the different methods of selling include:

Marketing the products and services plays a very important part in sales. Unless customers know about the product and how they can make a purchase, it is doubtful whether a company will have very high sales. The company has to pay for the product, which is called the wholesale price and then add a percentage to it, which is called the profit margin. The profit a seller makes on each item is how this seller often makes a living. Some of the ways sellers market their products to increase sales are through advertising on radio, TV and in newspapers. They also send out sales flyers in the mail. Online there are many ads on websites through which customers can also gain information about various products and make the purchases.
