Don't worry, you are NEVER charged for declined orders. Your bank or credit card issuer still shows those charges as pending until they receive final confirmation that those orders were in fact declined, which usually happens in the evening.

When you make a purchase online, your credit card is not actually charged at that moment. The card processor checks with your bank or credit card issuer to first make sure you have enough available credit to complete the purchase. At that time, your bank or credit card issuer places a hold, or pending charge, on the amount of the intended purchase against your card. The card processor then makes sure the other information you input (for instance, your address) is correct, and if all is well the transaction is processed. If not, such as if you enter an incorrect address, then the transaction is declined.

This is NOT a situation unique with this website, but it is how virtually all online transactions are handled.

PLEASE NOTE: Some banks or credit card issuers can take 48 hours or longer before they remove pending charges.
