That is a good idea G&Z, but you can't have the coolers open to oxygen or else all of the dry ice will be gone in virtually 12 hours.
I have never ordered steaks from Omaha Steaks either.
Also, is escape driving his own wine to Texas? If so, how many hours is his drive? My reason for concern is that if the dry ice evaporates half way through his trip, it would be a little difficult trying to buy dry ice from any old gas station on Highway so-and-so.
