If it's hot in your area (over 90° F), we recommend having your order shipped with insulated packaging and ice packs.

Here are a few things you should know:

• This will help your cultures stay cool for up to the first 72 hours of travel
• The package usually won't arrive cold
• This is ok, we just don't want your cultures to get too hot along the way (over 100°F)
• You'll still need to be home when the package arrives so you can bring it inside right away
• This shipping add-on doesn't count towards the $99 needed for free shipping

You can add Insulated Packaging and Ice Packs to your order on the Checkout page.
