All items are shipped in insulated food containers. The containers are made of foam and have a thickness of 3/4". Reusable gel ice packs are also included to keep the package cool until it arrives at your door step. Once you receive the shipment, please remove the food items from the container and either put them in the freezer or refrigerator. You will also be provided with a tracking number so you can keep track of when your goodies arrive. Should your package ever arrive warm, please inform us at firstname.lastname@example.org for either a refund or a new order sent to you on the house (of course!).
