Where we ship

United States addresses only. We do not ship internationally.

When orders ship

Orders with payment confirmed before 2:00 pm ET, Monday–Friday, ship the same business day. Others ship the next business day.

Some orders are reviewed by a person before payment is requested. Those ship after the review and payment are complete.

Carriers and rates

USPS Priority Mail: $15, free on orders of $250 or more. FedEx 2Day: $29. We do not ship via UPS.

Packaging and temperature

Lyophilized material ships at ambient temperature in protective packaging. From June through September we pack orders in an insulated mailer. For two-day delivery, choose FedEx 2Day at checkout. Store on receipt as described on the product page.

Signature

Orders of $300 or more require an adult signature on delivery.

Tracking

We email the tracking number when the order ships. Delivery status is on the carrier's tracking page, and order status is on your account page.

Address accuracy

We ship to the address exactly as entered, so please check it. Shipments returned to us for an incorrect address are reshipped at your cost. Packages the carrier marks as delivered are treated as delivered.
