You do not have to be home to receive the kit, particularly if your package delivery area is cool or at room temperature.
In that case, you simply need to be mindful of the expiry date listed on the transport medium in the kit (this is typically several weeks after the date you receive it).
Heat will not affect the kit unless it has been left out under the hot sun for more than a day. Our kit can handle temperatures of up to 50 degrees without effect.
When you do receive the kit, we recommend refrigerating the transport medium that arrives in your Legacy kit. This is optional but will extend its shelf life.
