title: PayPal Sandbox developer account ask me the enter Credit card information
body: <p>I have paypal sandbox test account.  I am trying it with HTML form. It displays a 'Buy Now' button on HTML page and after clicking on it redirects to PayPal site. Where it ask to login to buy product but after that it is asking me the credit card information. I think as it is sand-box account it shouldn't ask me credit card as it is for testing purpose.
