How same-day shipping from Alaska works

Every order is packed by hand in Anchorage and handed to USPS with tracking. Here is what “ships the same day” means, what it costs, and what we owe you if a parcel is late.

Research-use scope. Everything listed on this site is supplied for laboratory, analytical and in-vitro research only. Not for use in people or animals. Buyers must be 21+. This page covers shipping only.

The cutoff: paid by midnight ET

Orders paid by midnight Eastern time ship the same day, 7 days a week, except USPS holidays. Your tracking number is emailed as soon as the label exists, usually within minutes of packing. An order placed on a Sunday is packed that day, and USPS moves it from Monday.

The cutoff is about payment, not checkout: an order counts once its payment is confirmed. Card and bank payments confirm on their own; a Zelle payment counts once it arrives.

Why we ship Priority, not Ground

USPS Ground from Anchorage travels by surface, and it can take weeks to reach the lower 48. Priority Mail and Priority Mail Express fly, so those are the services we use. Your estimated delivery date shows at checkout once you enter your ZIP code.

What shipping costs

Thresholds are based on the order total after discounts. U.S. territories and international rates are on the shipping policy.

What we promise, in writing

The fine print (business days, holidays, free-shipping orders) is in sections 1 and 7 of the shipping policy.
