If the cost of offering credit card processing on your Web site has caused you to delay offering this to your Internet customers, you need to stop for a moment and think through the benefits. A great majority of purchases made over the internet are made using a credit card. And the consumers making those buys are more likely to order additional items, since they have the convenience of shopping with their card. The number of people using credit cards is growing, and that means every person with a card is a potential customer. And cards allow people to purchase more big-ticket items because they can spread the payments over a period of months.
