Bottled water
Dasani 20 oz. bottled water: $1.99
Buying bottled water harms the environment because it consumes resources and creates waste. And, it’s terrible for your wallet. Purchasing one bottle of water every day, even at only $1 per bottle, will cost you $365 a year. You can buy a reusable water bottle for less than $5 and fill up with tap water, which costs an average of $0.005 per gallon.
