We start processing all orders shortly after payment has been made and cannot add to, change or cancel orders once they have started production. Contact us as soon as possible if you would like to make changes to your order. If your order has not started production, we will be able to cancel, change or add to your order. If your order has already started production, we can help you place a separate order for any additional products. Add-ons typically ship separately from initial orders unless placed within very close sequence.
