We try our best to get all orders processed and fulfilled as rapidly as humanly possible. Often, your orders will be processed and packed long before our fulfillment partner can be notified of your request to combine your orders into one shipment. Furthermore, with consolidated orders, there's a higher likelihood of mistakes being made during the fulfillment process. To ensure that all orders are processed as quickly as possible, with less opportunity for error, we are unable to follow through on requests for multiple orders to be consolidated.
