If you have multiple charges and are paying online, you can pay all charges with one credit card transaction.
The last step of the registration process is the “Review and confirm” page. If a charge is involved, it will display two buttons:
“Invoice me” – Generates a charge only. Use this when you aren’t ready to pay yet.
“Pay online” – Generates a charge and starts the payment process. Use this when you are ready to pay.
When you click on either button a running total of your charges will be displayed in a small window in the lower right corner of your browser. This window will be displayed any time you have outstanding charges and you are logged in.
