can enhance the checkout experience by specifying tax and shipping rates in your account
profile. PayPal calculates the charges automatically for each transaction. In addition, you can
specify tax and shipping charges individually for items in the payment buttons that you create.

custom page payments in your account profile to specify logos and colors that match the style
of your website. PayPal uses the logo and colors to display the checkout pages. In addition,
you can specify logos and colors with advanced HTML variables that you add to the code of
your button.
