Accept Payments on Your Website
PayPal allows you to accept credit cards on your website simply and affordably. The standard program is free of monthly charges but requires your customers to have an account with PayPal. The professional program makes PayPal invisible to your customers but does not require that you get an expensive merchant account or gateway solution for only $20 per month. PayPal's low transaction fees apply in either program.
