Name brand bottled water is definitely overpriced. Store brands and off brands are more reasonable but still more than tap water - I assume we are mostly paying for the bottles. I spend approx. $2 a week on bottled water, refilling the empties with filtered tap water until the bottles get nasty, then I pull new ones. I know I’m overpaying but it’s not breaking the bank, and the bottles are convenient for lunches and trips.
They think we insist on Perrier!!!
I buy cheap bottles of water for the same reason. Refill them. I love the easy packets of instant Snapple. I buy the water and the Snapple packets at the dollar store. A heckuva lot cheaper than sodas, etc.
