When it comes to drinking water, you can save money by switching from individual bottles of water, to larger jugs. A whole lot of money, actually, especially given the fact that water is something you probably need to buy every day or every other day.
On average, self-service refill water comes at the price of 35 cents per gallon, which means that you will be spending $1.75 for 5 gallons. So, you can buy a 5 gallon bottle (with $10.88) and a water dispenser (with $26.59).
If you buy your drinking water from the grocery store, you will pay $5.78 for a 5 gallon bottle, which means you will pay around $1.16 for a gallon of water, a price that is more than three times higher than the price for refill water. So, by doing some quick math we can conclude that you will pay for the initial investment in the dispenser and bottle with the first 50 gallons of water. After that you will just save money with every gallon of drinking water.
