Refrigerated Shipping (Optional Upgrade)

For optimal product stability, especially during warm or humid weather, we recommend FedEx Overnight shipping with ice packs and a cooler. It’s a $29.99 flat rate within the continental U.S., already $10–$15 below our actual cost.

Free Ground Shipping (Default Option)

We also offer free ground shipping within the U.S. year-round (without ice packs or a cooler). This option is generally fine in cooler weather, but we don’t recommend it during periods of high heat.

Orders ship from Cleveland, Ohio, typically Monday through Wednesday to avoid weekend delays.

International Orders

We offer non-refrigerated international shipping for an additional fee. Refrigerated shipping is not available for international destinations.

Important Notes

• 
  Overnight orders must ship to a street address (no PO boxes).
  
• 
  Refrigerated items cannot be returned or refunded.
