You really should order two of these organizers...
...Perfect here in AZ. Before I leave home, I drop in a frozen water bottle full of water or a frozen blue ice packet in the cooler and take it right in the store with me, packing my items that need refrigeration to the check out. When summer days reach well over 100 degrees here, the car is at least 120 or more just sitting the parking lot and frozen foods thaw quickly without a cooler. Plus the organizer keeps everything from rolling out of the sacks. I have two of these and give them as much appreciated gifts. They are perfect.
