Orders are shipped from our Petaluma, CA facility M-F. In-stock goods are shipped out within 1 business day unless otherwise specified. If we are not able to meet this commitment a member of our team will contact you to discuss the timing. If you request a later shipping date at checkout we will schedule your order based on that request unless the request conflicts with one of our other policies.

Please Note: To ensure the highest product quality, it is our policy not to ship temperature-sensitive items when we know that they will sit in a carrier's facility over the weekend unless our customer specifically requests otherwise. Depending on the carrier and service level you select, we may delay shipment of your order.
