Why is there a charge on my card if my order was cancelled?

What you are seeing is an authorization hold, not a charge. When you make a purchase, an authorization hold is placed on your card to secure the funds. Your account is charged only if and when the merchandise ships.

If your order is canceled or did not go through, the hold will fall off your card. This usually occurs within 72 hours. However, your bank or credit card company ultimately determines when your funds will become available.
