If you would like to make a change to your order, please contact our customer service department as soon as possible at support@trayvax.com or (360)-738-8210. While we don't currently have the capability to add items to an order after it's been placed, we can either cancel the order or combine it with a new order and ship your items together. If you would like to purchase the same item, but a more expensive size and/or color, we can send you an invoice to cover the difference.
