Your credit card will be charged only when your order is packed and ready to ship, not when you place your order.
What you see on your online statement right after you order is not a "charge." It is a pending "authorization hold" placed by your card issuer that reduces your available credit limit. That hold will be converted to an actual charge when we process your order for shipping, or it will automatically go away after 1-3 days (depending on your card issuer's policy) if an order is canceled. That is how all credit cards work.
