Are the coolers pre-packed before delivery?
Yes. We pack them by day, in reverse order so that day 1 is on top of the first freezer and day 5 is at the bottom. Once they are packed, the freezers are placed in a walk-in freezer at subzero temps for a few days before they are ready to be delivered. The #2 & #3 freezers are packed w/ dry ice and sealed closed with tape. They should not be opened until the day assigned.
