CSS Payment Method???

[Sillyrab]

<p>So i was doing the CSS and when i went to submit I expected it to ask me for a credit card number to pay for the costs but the application just went on and finished saying the fee that i have to pay. Now i don't know how i will be billed, is it because i used a credit card to pay for the noncustodial form, or that I've paid on college board with a card before and it just used that one? </p>
