Where we ship
We ship within the United States unless the Site says otherwise. You are responsible for knowing the laws that apply where you live, including rules on possessing, cultivating, or shipping fungal cultures and on needles and syringes. We may decline or cancel any order we believe would break the law.
Processing and delivery times
Orders typically ship within 3-5 business days. Delivery dates are estimates, not guarantees. Living cultures are sensitive to heat and cold, so we may delay shipping in extreme weather to protect them.
Shipping costs and taxes
Shipping costs and any applicable taxes are calculated at checkout. Prices listed on the Site do not include shipping or taxes unless stated.
Address accuracy and lost packages
Please check your shipping address carefully. Risk passes to you when the carrier delivers the package to the address you gave, and we are not responsible for packages lost because of an incorrect or incomplete address. If a package is lost or damaged in transit, contact us within 7 days of the expected delivery date and we will work with you and the carrier on a resolution.
When your order arrives
Please open your package and check your order soon after delivery. If anything is damaged, wrong, or clearly not viable, see our Refund and Returns Policy.
