When you phone in a credit card order with an Internet retailer they will just process your credit card over the internet for you. Either way, your credit card information is transfer over a secured internet connection. However, when processed over the phone the operator can take your credit card number and use it.
Providing us your credit card number over the phone is less secure than through an internet transaction. In fact, for security and liability reasons, host-party.com does not collect credit cards numbers through any means. Instead, we have sourced payment processing to Paypal. They seem to have this payment stuff nailed.
If you are still concerned, you can mail your order to us and pay through a check. These instructions are found on the payment page on our website. Your game will be activated as soon as we receive the check.
