Shopping at HalloweenCostumes4Kids.com is so secure, it's safer than using your credit card at your local restaurant or store. Currently we accept American Express, Visa, Mastercard and Discover / Novus credit cards. We use a Shopping Cart provided by USA Merchant Center which is on their secure server. They use Verisign Digital Verification to create a secure link using Secure Sockets Layer (SSL), an advanced encryption technology. This encryption technology makes it impossible for anyone else to intercept your information. This is safer than using your credit card at the gas station. If you don't see the little lock symbol (in the lower left corner of your browser) in it's locked mode, you're not on a secure page. The only pages that need to be secure are the shopping cart pages where you would be providing information. That's why this page and the other catalog pages are not secure and show an unlocked lock. Remember, your credit card protects you, not the merchant against fraud.
