For your protection, we unfortunately cannot add additional items to your order and charge your credit card on file. We're not able to view or access any payment information that customers provide while ordering.
One option we can offer is cancelling the order you've already placed and having you a place a new order with all the items you'd like!
If you wish to cancel your order and place a new order with the additional items, please contact us using the "Submit Request" link at the top right of this page. Please note that our warehouse often ships orders within 1 business day, so order modifications are not always possible.
