Saving money on food expenses: Water

I love water. Between me and my girlfriend we drink at least a gallon of water every other day. If I bought bottles of water that would be roughly from 3 to 5 bottles a day. Water is a very healthy liquid to drink but it also can be a very expensive beverage if purchased individually. Lets do some math:

• One 16oz bottle of water costs roughly $1.00 or about $8 a gallon.
  
• One 24 pack of 16 oz. bottled water costs roughly $5.00 or about $1.67 a gallon.
• One gallon of spring water costs roughly $0.65 or about $0.65 a gallon.
• One gallon Wal-mart refill costs roughly about $0.30 or about $0.30 a gallon.
• One gallon Water refill with own filter costs $? or about $? a gallon.
  

Here is an idea on what you can do to save money on drinking water expense. First buy a gallon container of your favorite drinking water. When you have finished with that gallon bring it into your local grocery store and refill it. The cost is very minimal with most grocery stores being around $0.25 to 0.30 per gallon. We normally fill up 5 single gallon jugs on a single trip and that can last us for a good while. Then you can use that water to refill bottles, cooking, or just plain drinking. Enjoy!
