You must always try and use a safe and convenient electronic payment option or just send your payment. The usual methods of payment usually are:

Debit or credit card: Your payment will be processed by a payment processor who will charge a processing fee.
Electronic funds transfer: Every user must have a secure Internet browser with 128-bit encryption in order to access the site.
Check or money order: Mail your payment to the address listed on the notice or instructions

Just remember, do not send cash through the mail!
