If it is estimated that you will incur any charges not covered by promo credit or sponsorships, you must enter your payment information before submitting the request. Your card will not be charged until your promo balance is depleted or until sponsorship funds run out.
Adding a new payment method
Enter your credit or debit card under "Payment Methods" in your profile. Don't worry; we use a very secure payment processing system called Stripe, so your information is safe.
