I strongly urge against the styrofoam coolers. They aren't much cheeper than regular coolers and they usually break within a few hours. Especially if you have heavy things in them like pop or beer. Styrofoam coolers cost about $4-$8 and you can get a regular cooler for $10-$20. My friend stopped in my town and picked up beer for the beach and paid $5 for a styrofoam cooler at the gas station. He got to the beach, carried it to the water, set it down, and it broke to pieces. He could have drove 1 mile down the road and got a real cooler for $10. The best place to buy a cooler is Dollar General or Family Dollar, there's usually one of those in most towns, just ask the gas attendent.
