When you click "submit" you will be taken to a Paypal payment screen. You do not have to use a PayPal account to process your payment. You will have two options:
1. If you have a PayPal account, you may login to complete your payment.
2. Otherwise, you may select "Pay with Debit or Credit Card" instead, without needing a Paypal account.
Your request will not be processed unless payment has been received.
