When temperature highs or lows fall outside of our safe-to-ship thresholds, we postponed FedEx 2Day shipments for the time being. If you receive an email to this link and have an order awaiting shipment via FedEx 2Day, you may purchase this flat-rate upgrade to FedEx Standard Overnight shipping. During checkout, please choose the zero-dollar "Flat Rate Shipping" option. We appreciate your patience and understanding!
