Ozonated water question for the chemists here

Hi all, the water store down the street where we buy our purified water also sells Ozonated water. I bought it before and it is different.  My question is, if the water was indeed ozonated,, I have recently read that ozone breaks down fast and that it should be consumed as soon as it's made when drinking ozonated water.  So if I'm buying a 5 gallon bottle of ozonated water from this guy, obviously that water is going to sit on the counter for a while as we consume it.  Is it useless to purchase his ozonated water?  Or is it fine to store it for a while?
