家园 瓶装水一瓶1美元相当准确

"The [bottled water] industry grossed a total of $11.8 billion on those 9.7 billion gallons in 2012, making bottled water about $1.22/gallon nationwide and 300x the cost of a gallon of tap water," Colas says. "If we take into account the fact that almost 2/3 of all bottled water sales are single 16.9oz (500 mL) bottles, though, this cost is much, much higher: about $7.50 per gallon, according to the American Water Works Association. That’s almost 2,000x the cost of a gallon of tap water and twice the cost of a gallon of regular gasoline."

全美瓶装水平均价格是1.22美元每加仑。但是所有瓶装水中,2/3的销售是500ml装的瓶装水,平均价格7.5美元每加仑,折合0.99美元每500ml。

从walmart买整箱的瓶装水可以省钱是没错,但平均而言,瓶装水一瓶1美元一点也没错,反而相当准确。当然我不认为周是做过调查给的数据,瞎猫也能碰上死耗子嘛
