Any tricks to rapidly cool refrigerator?

We find out we can go at the last second all the time. I go out and start the fridge, put a few frozen jugs of water in that we keep in the bottom of the deep freeze and go to the store for food. Once I have the food, I pick up Honey and the dogs, put the food in the fridge around the jugs and take off. The fridge is barely cooling off but the jugs keep everything cold until it catches up.
