My usual course of action is to get a milkshake, then drink it while perusing the ice cream flavors; When I finish it, grab about 5 gallons of ice cream, buy it, go back and cram it in a cooler chest in the car, and go home.

My fridge now has 5 gallons of ice cream. I'll keep 2 half gallons, take one to my parents' on Sunday, and take most or all of the rest to work Monday and feed my cow orkers.
