Adding a Buy Now button to a product page on your Web site is the simplest way to support e-commerce payments on your Web site. You generate the code for the Buy Now button by filling out a form on the PayPal Web site (also known as the Button Factory). After filling in the form, PayPal generates the code, which you can paste into the code for your Web page. There are a number of reasons why you would want to add Buy Now buttons to your Web site, including these:

• Buttons are easy to add to your Web site. Because PayPal generates the button code for you, you don't need to know how to write advanced scripts to make the e-commerce functionality work.
• There are no additional fees or costs to add PayPal buttons to your Web site.
• Because PayPal saves all transactional data in your Account History, you can download and analyze the sales data whenever you want.
• Taking advantage of the ability to customize the look of the buttons, you can ensure that your Web site looks professional, which makes buyers feel more confident when they decide to purchase an item.
