Simply put - we don't sell or give any of our customer information away. We consider your information to be company proprietary information only. If ordering by credit card, your account number is not kept in the shopping cart site database. This is why, every time you order from us, you will have to re-input your credit card number.
Please note that if you wish to have your credit card purchases shipped to a post office box, we will still need your physical address, (the address to which your credit card statement is mailed), in order to verify the credit card is not a lost or stolen card with the credit card company. This is for YOUR protection as a consumer. It is too easy for someone to make a purchase with your lost or stolen card if no measures are taken to verify that it is an authorized purchase.
