Another thought I shared with “She Who Must Be Obeyed” the other day. An easy way to stash some extra water for emergencies.
Most chain grocery stores have the 5 gallon polycarb water bottle exchanges. $14 for a new full jug. $7 with exchange. This water is good for something like 12-18 months I think. Buy two and once a year dump the water and get new refills. $14 a year. Or more if you want to up it.
For $14 at Sam’s Club you can buy three cases of 1.5 liter bottles of Crystal Geyser water that will keep for decades.
Of course, you should be drinking that stuff anyway, if you want to live that is, so why buy fake drinking water at a higher price?
