Publix... be careful, though, a little goes a long way. I was transporting some custom ordered ice cream from GA to WV one Christmas. Packed it in a cooler with LOTS of dry ice. It stayed cold, REALLY COLD, by the time we got there, nothing we had in the kitchen would touch it. Had to leave it sitting out on the counter for over an hour to even get the edges thawed enough to get any out of the carton.
