I was at kroger today and came up on some nestle water 3 liters jugs...reg 79 cents and they had them to where you bought 10 of them you'd get them for 49 cents so I bought like 18 jugs for like $9.00. They expire next year, what's the best way to make sure they last more then that? They are stored in a room on the side of my garage that has ac, it's part of the house. Cool thing is...the jugs at the bottom have a indentation so that they could be stored on top of each other. I want to go back and get more....but need to know if they will last beyond the exp. date.
