Do I have to register with PayPal to pay for ePort Money Transfer?
No you are not required to register with PayPal to pay for ePort. You may choose to register with PayPal if

1) you would like to pay with bank check or PayPal issued credit card not with major credit cards such as VISA, MASTER CARD, AMEX, DISCOVER
2) you use any of the payment methods including all the major credit cards, but in the future when you pay online instead of entering again and again your account information you want just to login to PayPal and pay quickly.
