Many business's have a toll free number which enables their customer's to contact them and not have to pay long distance. This gives them the convenience of talking to a customer service representative, if there's a problem or they need to ask a question about a certain product. If your have a service or business and still don't have a toll free number, then it would be important to you to get this right away. Just think of all the business your missing, because customer's don't wish to pay a toll fare.
