A Cold Pack will provide up to 48 hours of temperature control during transit. If the temperature is above 75 degrees at your recipient's destination, please add a Cold Pack to your order. For destinations outside the Charlotte area, please select an Express shipping option as well. This is necessary as Cold Packs only provide 48 hours of cold power. When the temperature is unusually hot, (i.e. above 90 degrees), we may have to hold your order until the weather cools down.
