We will ship your order as fast as we can, this is usually within 5-10 business days. Although we are known for our spore quality throughout the world, it’s still just a small-batch operation. Due to increasing order volume, it is possible for your order to be delayed longer than our usual shipping time during peak holidays or busy periods. Your order will be shipped, we promise. If your order is delayed, it’s likely because we have to make a fresh batch of what you ordered. Rest assured, your batches are likely as fresh as your order. If your order is delayed in shipping, please contact the carrier, not us.

All standard orders ship via tracked USPS First Class. You also will have the option to upgrade to USPS Priority Mail, UPS Ground, or UPS 2nd Day air. Shipping option does not include processing time and may take longer than the “2 day” as promised with that service.

Canadian customers have two forms of shipping offered – Standard International First Class & Priority Mail International. Australian customers have only one Priority Mail option.

We cannot ship bulky or large items to Canada or Australia.

If you are ordering from outside the United States, please be sure to remember we take no responsibility if customs seizes or destroys your package. We cannot control this and will not offer refunds or discounted replacements. Please order at your own risk.

We do NOT ship cubensis samples to California, Idaho, or Georgia. It is illegal to import these spores into the state.

Failed Deliveries and Incorrect Shipping Info:

If you enter the incorrect shipping address and fail to notify us before being shipped out, you must replace your order. We do not reship returned orders free of charge. If you fail to enter the correct address, that is not something we have the power to know. We also have this policy because we do not reship items that have been returned to us. Returned packages are often beaten up and damaged. If you are able to notify us prior to shipment we will gladly change the address for you without hassle. Please double-check when placing your order!

If your package does not arrive but the tracking number says delivered please follow these steps as set forth by our carriers:

  1. Check with anyone in your household to see if the package is somewhere you were not expecting.
  2. Check with any neighbors to see if the package landed with them.
  3. Contact your local post office or UPS to let them know of the failed delivery. The carriers have GPS tracking for all package scans and this information is very helpful in verifying failed deliveries or verifying successful deliveries.

We reserve the right to contact the carrier regarding your order if you are reporting a failed delivery to us.

Failed deliveries are not replaced unless the carrier can confirm the failed delivery. Reship costs will be determined on a case-by-case basis. We are not obligated to reship due to failed delivery and will be decided at the sole discretion of Grumpy Gills Fungi.

Orders that are reported to be arriving late or delayed will not be considered for reshipment until tracking status has not updated for 10 business days.


Payments must be made in a timely manner. If you violate our terms and submit payment for an order being sent to California, Idaho, or Georgia it will not be automatically refunded. It is illegal to import spores to those states.

CASHAPP: We expect CashApp transactions to be paid at the time of order with the correct order number in the notes.

EMAILED INVOICE: It may take us a small amount of time to send you an emailed invoice if that option is selected. We expect the invoice be paid within 12 hours of receipt so that we can ship your order ASAP. Thank you.

We do not offer refunds, however we will send you a replacement for the cost of shipping in the event you can provide microscopy photo evidence of spore degradation or foreign objects in the solution. Delivery date reflects date delivered in the carrier tracking page.

We do not offer replacements where there is hinting or direct mention of cultivation or spore germination. We do not condone our product for uses other than microscopy, art, and collectively related purposes. You will be ignored and barred from future orders if this occurs.
