Note to the NEST users in the U.S.:
There is usually inventory in the US of A. If the shipping method shows as ‘Fedex’ on checkout then some items in your order are coming from the Shanghai warehouse. Try ordering just the relays alone and shipping will usually show USPS which means the items are in stock in the states.
