For the best product stability, we recommend FedEx Overnight with ice packs and a cooler. It’s a $29.99 flat rate in the continental US, which is already $10–$15 off our actual cost.

We do offer free ground shipping (without ice packs or cooler), but it’s only a good idea when the weather’s cold. Orders ship from Cleveland, Ohio, usually Monday–Wednesday, to avoid weekend delays.

No PO boxes for overnight shipping, please. And remember: Refrigerated items can’t be returned or refunded.
