If you have been charged $1.00 (or multiple charges of this amount, depending on how many times you submit an order) - there is little cause for concern, you have not been charged.
Charges in the amount of $1.00 are authorizations on the card to make sure all information is valid. Some banks then set aside the $1.00 as pre-authorized. It hasn't been deducted it's just set aside in our name by the financial institution but we do not actually have the funds. If the transaction did fail, the money will be released back to your account shortly.
