Even with all the moves to "go green," people still buy bottled water, for the convenience or because they think bottled water is safer than tap water. Even if you recycle your plastic water bottles (and you'd better!), we still advise against buying bottled water unless you're prepared to pay a 4,000 percent markup. Yep, you heard us correctly. Bottled water by the case can wind up costing you more per unit than gas for your car.
That's because it takes about five bottles of water to make the plastic for just one bottle of water. And many brands of bottled water are actually just pulled from municipal taps. So you're better off purchasing a water filter and drinking out of a glass.
